TL;WR:
DHS/SHS are poorly balanced, especially when compared to other upgrades. SHS builds are straight up inferior. Set SHS engine sinks to 2.0 to make SHS viable and make DHS less of a definite upgrade.
The Problem:
DHS are, quite simply put, a straight upgrade. The only reason not to use them is if you can't afford them. Naturally this presents a problem to the games balance as it essentially means that an established player gets a ten tonne/ten slot advantage on their mechs (before additional out of engine heatsinks, which only increases the advantage) over newer players or any trial mech. You have to make a decision on whether ES/FF/Artemis is right for your build, the answer for DHS is always YES.
My Proposal:
Set Single Heatsink Engine sinks to the same value as doubles (2xCurrent value). Outside the engine they work as they do now, but both heat sink types both have the same baseline heat cap/dissipation.
Effects:
Better balance. A SHS mech is not at a huge disadvantage against a DHS mech.
Better choices. Although DHS will still be better for most builds removing the huge Engine Heatsink advantage means that the space/tonnage choice between SHS/DHS actually matters and in some extreme builds SHS may be a better choice. More options = Better game play.
Better trial mechs. One of the greatest barriers to getting into the game is the poor viability of most trial mechs. Part of this is down to armament (I'm looking at you Cicada 3A), but for most of them the real disadvantage is the lack of DHS. A trial Atlas-D has 20 SHS, for the same amount of slots in DHS the same build would have an effective 24 SHS, plus seven extra tonnes to spend on better weapons, armor or a larger engine. Setting SHS to the same engine rating as DHS still gives the DHS Atlas a decisive advantage, but no longer makes a SHS mech laughably inferior.
Better weapon balance. A weapon with a heat/damage ratio balanced for SHS becomes twice as effective with DHS, for DHS half as effective for SHS builds. A PPC is a sensible choice for a DHS build but a joke for a SHS one. Setting HS at the same base line makes for better overall weapon balance.
<250 Engines
TL;WR:
Engines under 250 are disadvantaged by requiring extra external heatsinks, having less internal heatsinks (and thus benefiting far less from DHS upgrades) and by having slower movement/turn speeds. Slower speeds are enough to balance them, the added heatsinks disadvantages are unnecessary and make them needlessly disadvantaged.
The problem:
Engines under a 250 rating are an extremely poor choice because of the requirement for extra out of engine HS. This is unnecessary as they are already balanced by the lower speed/less in engine sinks. Small engines are never a good option for Assaults/Heavies as the decrease in speed is worth less than the increase in free weight, but they're supposed to be a viable choice for lights/mediums. As is, that's not the case. A lower rated engine is already disadvantaged enough by the decrease in speed and in engine heatsinks (making DHS much less effective), forcing the player to take extra tonnage and space in out of engine heatsinks makes them completely useless. This constricts light/medium mechs to higher engine ratings and makes the lower rated engines completely unused.
My proposal:
Revert to the old system without the min required HS and set all engines to 10 HS. A 200 rated engine is already balance against a 250 by lower speeds, it doesn't need further handicaps. A 150 Commando is disadvantaged enough by running <100kp/h, forcing it to take 4 tonnes of heatsinks is just kicking it whilst it's down. This is even more of a problem when it comes to DHS, a 250 engine gets 20 free SHS with DHS, a 150 only 12.
Effects:
A weakening of the Faster = Better effect for lights, a lower rated engine actually gives a meaningful advantage that makes it worth considering for some builds.
Smaller lights are better balanced. A Commando will never have as many guns as a Jenner, but it makes up a little bit of the distance if it can run at the same speed with a smaller engine and use that extra weight to narrow the tonnage gap a little.
Smaller mechs benefit from DHS. A Commando can only have a max engine of 210, this puts it at a massive disadvantage to other lights as a DHS upgrade only gives it 16, rather than 20 in equivelant SHS engine heatsinks, leaving a mech like the Death's Knell massively disadvantaged.
