Creating a fair matchmaking system is always a struggle especially when you factor in a portion of your playerbase will do everything in their power to abuse it to their advantage.
A lot of it is still unknown, but I thought I would point out some of the issues PGI will have to consider before they release this to the public.
Purposefully sinking your ELO to fight noobs and win more.
In some games the term is called Lossbotting. Players will spam lose matches until the matchmaker starts placing them against legitimately bad players. He then wins 10-20 games in a row and then follows up by spam losing 10-20 in a row. Once they've made it to noob-ville, they maintain a 50% win percentage so they never leave.
Bringing in the dedicated loss botter(s) to sink your team's overall ELO average
So your team is starting to face off against the real opponents and you're struggling to get a win. What do you do? You all blame cheesy builds and bring in your buddy with the ELO score of zero to lower your team's overall average. Ideal scenario would be to bring in enough zero ELO people sink it down to 1300 where the noobs start. The fact that you have teams of 8, means it's easy to subtly switch one or two players in and out to keep your ELO artificially low.
If I were PGI, I would consider creating some sort of fudging effect where you take the highest and lowest rated players and give them less impact on the average.
Smurfing
Smurfing is the term for creating a fresh account so that your ELO is back to noob-level. You then face off against a bunch of legitimate scrubs and wipe the floor with them. I honestly have no idea how PGI could combat this, but it's something they should keep in mind. If this becomes rampant, it will just ruin the beginner experience.
Incentives to Abuse the Matchmaker
Basically, the more of these that exist, the more pressure there will be to abuse matchmaker:
- More Money/Experience for beating a higher rated team: if the game rewards upsets, people will artificially create upsets by lowering their team's ELO.
- Achievements/Fluff Rewards: In Starcraft 2, there were people who lost games to bring their ELO to the lowest point possible where only the ultra terrible and other farmers existed. They then traded wins with each other to farm achievements and portraits for their accounts. This trivialized many of the impressive achievements out there. If MWO creates stuff like bobbleheads for 1000 wins or something. People will farm them.
- Letting really good players match against mediocre players: If you have 4 really good players paired with 4 really bad players. They will almost always win against 8 mediocre players. be careful about people stacking teams.
- 4 man premade rated the same as 4 pugs: If a team of 4 premades are rolling an 8 man pug and are treated the same as 4 random pugs, you're going to have trouble with fair matchmaking. There should be some sort of temporary boost to their ELO to face them against slightly tougher PUGs. Of course ideally the matchmaker would try to split premades in the search queues up evenly and against one another.
