Heat is cumulative unless you cool down.
Energy is not cumulative you automatically get energy back at the end of your turns.
So If as an example; you have a heater that does 189 heat with 1 shot, is that the same thing as 189 energy drain with 1 shot? It seems a lot of people think it is.
To me it is not the same thing if you are heated to 189 that stays with you until you give up a turn and cool down, energy drain don't stay with you, you have to keep draining and they get back recovery at the end of their two turns.
If you are shut down you skip both your turns if you have 0 energy you use 0 energy weapons, stomp, utility weapons, 0 energy drones etc.
What do you think?
