Well, kudos for the community interaction and best of luck.

I have to say the current distribution of players surprises me, I thought a much higher percentage of the player base was tier 1 because of the current upwards bias of the psr calculation. I'm also surprised to see so many players in tier 5, is that because there are a lot of new accounts?

The limits on PSR rating may have a side-effect that hasn't been mentioned I think:

When the lowest ranked players play, with some having 0 rating, they can not go lower and therefor the total sum of the PSR changes in that match will be positive, causing an inflation. This isn't necessarily a bad thing but something to be aware of.
It will push lower skilled players into higher tiers.

The same goes for the top: top players can only push each other down.
The model that Nightbird linked shows this as instability, but I think it actually reveals that only players between 1000-4000 rating see the mobility of the new PSR rating.

It will be interesting to observe.

You know why win/loss should never be introduced into this sort of thing in quick play? Because of modes like conquest. When ******* just abjectly fail to give a **** about the objective and the other team does. Or when instead of just dipping a toe in the circle, your team pisses off to skirmish merrily three grid squares away from it.

Otherwise, do what you will.

Well, we know the update will fail because:

1. the formula fails to stabilize people at any PSR value other than 0 or 5000 (forget that bell curve, 0 chance of that happening)
2. groups are given a large unfair advantage in the formula, solos get ready
3. number of stomps will not change (and may get worse for two months)
4. 60% of the player base will be sent - fast or slow - to Tier 5 for being below average
5. T5 players are 2.5x more likely to quit MWO

Because Math is not an Opinion.

So rather than waiting for 2 months to see proof of whether 1+1=5, I give you the result now:

P.S. The tier/population graph needs to be players*games to present the relative number of people in each tier as relevant for the queue. See 5 above.


I would very much like to see a response to this from PGI, they seem to be very valid concerns.

On the contrary, that's exactly the reason why w/l has to be the main factor.

Those players in your example that failed to play the game mode were objectively playing bad in those matches, and that lost them the match. But their avg matchscore might still be high, only their lower w/l reflects the fact that they are bad at conquest.

I have to admit I don't get the math, I just hope it will work out.
What I like is to see that PGI actualy takes in stuff sugested by the community and tries to improve on that.

I hope to see more of that cooperation and maybe at some point a mapmaker for players?
I bet there will be people willing to work on those too.

Everyone counted three times? Once per month? Plus every tier change counted, ie, PlayerX in May was in tier 4 for two weeks and tier 3 for two weeks so was counted twice that month?

Otherwise I don't get the player base numbers vs what we have heard previously.

well, and what if the current avg matchscore is 222, right in that zone that doesn't go to extremes?

Given that quote was given to us a few weeks ago by Paul Inoyue, how does the current matchmaker implementation work within the current playerbase limitations, rather than in a massive hypothetical playerbase that does not log in simultaneously or much at all, apparently.


well, it'll definitely be better than it is currently. it'll help MM a lot knowing to separate a multiple-times world champion from a 30th percentile player, which might balance matches more, even with the current MM, as it now knows what players NOT to put on one team

Sorry, but I think your models aren't entirely correct since they seem to be based on the assumption that the average players performance will be static across all tiers. This is not the case.

Apart from the extremes at the top and bottom of the MS/performance scale, there's a strong indication that people will get higher AMS in the lower tiers 4 & 5 and will get lower scores in tier 1 & 2. This, imo, will prevent the envisioned scenario where you will end up with 60% of active players in T5 and will lead ultimately to a normal distribution.

I think, even though I voted for a different approach, the proposed changes would be a good change. Maybe the implementation and reset could be combined with some longer lootbag-type event to encourage people to play more?

One think that's not really clear to me is the situation of people starting the game; would they start in T3 or T5? Remembering the rather "brutal" start and steep learning curve for me, I think it wouldn't be a good idea to let them start in T3 where they could end up facing T1-players.

It may have taken a couple of years, but right now, I'd like to think that the blatant absurdity and irony of Russ's quote in my signature block is now just a bit less so.

I for one am pleasantly surprised that this effort appears headed to actual implementation. I still don't think it will change much at this point, but I have to applaud PGI for making the effort to engage the community, and give kudos and respect to those community members who put effort into trying to provide real, workable, solutions. Truly uplifting.

Cool, now it's time to check i out. Props for PGI and Jay Z and all... There is nothing to assume right now, just to check it. Some values may be changed. Interesting thing about T-4 to T-1 players.

I'm looking forward for more Posted Image

In my opinion the weights are too heavily counting in the W/L and not enough on the match score, but I am glad you are putting in the new system where the values can be tweaked a little.

Setting the W/L factor to 1 generates a more ideal outcome... again in my opinion.

A strictly W/L rating will simply drive everyone to the middle and leave very little to the curve. It will favor groups even more than 2C since people that drop together are more likely to affect the outcome of the game. It basically is a faster way of crumpling your metaphorical bridge.

A grand total of 6-ish responses in 6 weeks (most of them omni-directional announcements) is an improvement over previous radio silence, but let's not go crazy here.

The community did a great job doing consultant level work at the best possible rate for PGI, though.

If the PSR doesn't assign higher static values to people with higher skill, and lower static values to people with lower skill, then it is blind when making teams when trying to put an equal amount of talent on both teams.

Past MS performance has a weak correlation to winning, like mech tonnage and KDR. WLR has strong correlation.

Well, that's where we have to agree to disagree Posted Image

Problem is, and the reason why I doubt that I would be able to change your opinion, that, in order to come up with a comprehensive simulation of the future distribution of players across the different tiers, I think we simply do not have the necessary data Posted Image

Hence I don't think that the posted analysis can be used to reliably predict the player distribution in, let's say, 3 to 6 months after the tier reset and the implementation of the new PSR calculation.

If you're talking about the graph I linked for (1) I agree. Xiphas already said in his post his model is very simplified. It does show that Jay Z's solution diverges, this part is absolutely correct and it's the point I noted in (1). There's no simulation of the expected WLR for players across the skill spectrum nor a prediction of stomps but I did that in my simulation linked. You can note a decided absence of such support for the first post. I think Jay Z tried to do a sim but it confirmed what we know, he can correct me if I am wrong.
