With the proposed 1.4x multiplier, after November 6, any current build over 16 DHS will have less heat dissipation than it does currently.
(Nov 6) vs (Current)
17: (23.8) vs (24)
16: (22.4) vs (22)
Realistically, you mount 6-10 criticals worth of weapons, depending on the mech. That leaves 20 or 21 as the maximum realistic number of DHS you can cram in. That of course leaves no room for endo-steel, ferro-fibrous armor, or an XL engine.
Since that is the maximum reasonable number of HS and PGI likes the balance of the current system...
I propose a multiplier of at least 1.5 so the top-end for DHS heat dissipation stays at least where it is now.
Old: 10 + 11 * 2 = 32
New: 21 * 1.5 = 31.5
Reason 2
Effectively, this change is making DHS even better for lighter mechs relative to heavier mechs. Even if a light had an effective 30 heatsinks (10 engine + 5 extra), they won't be able to mount enough heavy weapons to make use of all that heat capacity simply due to chassis weight & hardpoint restrictions.
In the middle, you have heavy & medium mechs which can make the most use of this. They have a fair amount of tonnage available and a good selection of hardpoint to mount a few heavier weapons.
The change favors light mechs that mount 16 or fewer DHS over medium/heavy 'mechs and will increase the already amazing popularity of light builds.
Reason 3
Many (most?) assault builds gain little or no benefit from running DHS with such a lower multiplier. If assault 'mechs can't dissipate more heat, they can't put out more damage than a lighter 'mech.
On the other end of the spectrum, heavy 'mechs can run out of criticals long before they run out of tonnage and have the hardpoints to choose whatever weapons they want to use those sinks. There isn't a whole lot of point in them using 3 criticals on a DHS just to save weight. In fact my favorite Atlas builds have 30+ single heatsinks. With a 1.4 multiplier, there is no way to get above ~30 heat dissipation with double heatsinks and still mount assault-class weaponry. (Assaults can only get that high with DHS because of the added heatsink slots on engines over 275)
