I didn't want to get too much into the actual mechanics of heat in my OP, but I'm glad you brought it up. In TT, the amount of heat you can "soak" with no penalty is the number of heatsinks (or DHSx2). Using those numbers, you could generate 10 heat in a moment with just your engine heat sinks, and then bleed it off at 1 heat every second (@ .1HPS per SHS, or 2 heat every second @ .2HPS per DHS) with no penalty. If you went above the heat soak capacity of your mech, you would run into the effects from this translated heat scale from TT...
So, looking at this scale, a 6 PPC stalker with 20 DHS could soak 40 heat, that would still put it at 20 on the heat scale, which is a pretty stiff penalty, as it's now immobile (even if it's not shut down) for a few seconds, plus a good chance for an ammo cookoff. That's after just ONE alpha. A 4 PPC stalker build with 20DHS would still be viable if only this portion of my post was taken into consideration, but in conjunction with everything else, the 4 PPC stalker wouldn't do well against a mech with a variety of weapons and a heat efficient build.
Edit: Almost forgot to add, at walking speed (2/3 max speed) you're generating .1HPS just with movement, at running (over 2/3 max speed) it's .2HPS. Not to mention jumping (1 heat point for every 30m jumped)
One crucial aspect to me is:
You can fire 4 PPCs about 3 times in 10 seconds and overheat on the third alpha.
20 DHS puts you at a heat cap of 64 (without any efficiencies) and a dissipation of 3.4/sec or 13.6 heat over a PPCs cycle time:
Alpha 1 at 0 seconds: 32 Heat
Alpha 2 at 4 seconds: 32 Heat + 32 Heat - 13.6 Heat = 50.4 heat
Alpha 3 at 8 seconds: 50.4 Heat + 32 Heat - 13.6 heat = 68.8 heat. => overheat (and only at 107.5 %of max threshold, far away from any heat damage penalty PGI has suggested so far.)
Add 10 % heat cap from efficiencies, you reach a capacity of 70.4, and you can alpha a 4th time even.
Alpha 4 at 12 Seconds: 68.8 heat +32 Heat - 13.6 Heat = 87.2 heat => overheat (and at 123 % of max threshold, this might reach the critical heat damage region mentioned somewhere.)
That's a potential of 120 to 160 damage in 12 seconds. There are not many builds that can compete with that, and 160 damage is enough to core any Atlas.
I understand why the heat threshold is 30 + heat sinks. If it wasn't, you could not possibly fire anything more than 3 PPCs together, and there are mechs in lore that can alpha 3 PPCs. But the math doesn't work out with this. By allowing 3 PPCs to alpha once, you also allowed 6 PPCs or 4 PPCs to alpha
multiple times within a 10 second time frame.
The table top rules do not actually require that an alpha occurs within a single millisecond. It occurs in a 10 second turn. So maybe a mech like the Warhawk or the Awesome 8Q or 9Q actually chain-fires all weapons in this 10 second turn, with just enough time between shots to allow the dissipation to catch up and allow the next PPC hit?
A fixed threshold at 30 would then also work for MW:O.
