Then you can give a chassis/variant quirks for higher/lower heat threshold in order to tune for balance.
For example, set fixed heat threshold at 30. Then give Awesome a quirk that raises its heat cap to 36. He can shoot 3 PPCs simultaneously and not shutdown.
Any other mech tries it and instantly shuts down.
Lower heat threshold also prevents high initial burst damage spam, which is really what cripples/kills mechs quickly when the fight starts.
