I decided to do some math for my own entertainment, and discovered some interesting numbers:
Using a Hex being 30 meters, and using the published 'mech speeds in KPH, I calculated that all PGI 'mech speeds come out to a TT "Turn" of *10* seconds. Half of the TT speeds also came out to *10* seconds, and none of the other half were the same as each other.
Taking that value, and applying it to Heat Sink dissipation: Single Heat Sinks dissipate *0.10* heat per second, and doubles dissipate *0.20* per second.
If we set the heat cap at 40, and changed the skill nodes that increase it (so it's a hard-and-fast cap of 40), but we increase heat sink efficiency (and continue to allow skills that increase that further), then it will be impossible to fire high-damage alphas (and will pretty much negate ghost heat, since a hard-cap of 40 heat is about where most ghost heat triggers, anyway), but if you chain fire, then the heat from your first two weapons will be completely dissipated by the time you've triggered your third weapon.
I think the limits on Gauss Rifles should be that you can only fire one Heavy Gauss at a time, two regular Gauss at a time, and three light Gauss at a time. That's 25 damage, 30 damage, and 24 damage, respectively. You can still chain them, as you can do now if you want. It'll just prevent placing any damage beyond that in the same spot. More than likely, the next shot will hit a different component.
I know that my Adder-Prime and ACH-C (both stock from the store, but fully skilled) seemed to run really hot, and I saw Kanajashi make a 4 PPC Warhawk run super cool. Mostly, though, I didn't notice much difference in most of my 'mechs between live and PTS.
Oh, and the situation where you'd be firing continuously for more than 30 seconds? Fighting for your life at less than 100 meters. (AKA: "Brawling").
EDIT: I did my math wrong. I attributed the "Speeds" to Walking speed instead of running speed. Correcting my error, a TT "turn" is 10 seconds, and heat dissipation is 0.1/s for singles and 0.2/s for doubles (where the PTS 2.1 placed the values).
