The 10 HS in the engine (250+ rating) is the default amount to allow the engine to work effectively. Without that many mechs would not be able to equip enough external heatsinks to run a proper payload.
The issue is that people want SHS to be a meaningful, viable option when there is a definite upgrade available. And that is cause many do not want to step out of their 3025 shell.
It is funny we still have the now GH 1.0 and likely soon ED 1.0 (once it goes live).
Heat Scale CAP - 30 base + SHS/DHS capacity. ONLY 1 penalty when at/exceeding 100% = Shutdown.
SHS originally was a 1-1 ratio, so 30+10(engine SHS)+ 1*external SHS
DHS - when introduced DHS was finalized at 2.0 engine DHS + 1.4 external DHS. 30+20+1.4*external DHS.
Finally GH 1.0 AND exceeding heat cap damage (shutdown/CT Internal Structural dmg) or override/random Internal Structure damage.
So, a Heat Scale which the capacity could simply be increased by 66% if just using the engine's DHS, and a heatscale that still has NO OTHER negative threshold except for what happens at 100%+ mark.
PGI has shown they have the ability to set movement/agility penalties that were eventually given to a Clan mech after losing one ST of an cXL engine, then they have now also broken up the Heatsink components with the ability to give them separate values.
The question is why has PGI not moved in that direction? Likely due to how we do not like change, they are also comfortable where they are at, and may be they do not have the right people to make it happen.
