well i dont know if someone else had the same idea before but i think that new drones that heal you a bit or cooldown your heat could be a great idea to rebalance the game, you know...for those heavy mechs that doesnt need that third atack but more heat/energy. like a drones that coolsdown 20 heat everyturn but uses 30 energy
please let me know what do you think and ideas do you have about these drones

It would be totally unnecessary because contrariwise, if new drones that heal you a bit or cool down your down are added, it could probably cause an imbalance between combatants. Furthermore, if you want to know what do I think: the movement made by your mech when you click on the shut engine down option can very effectively reduce the heat and in my opinion even the low level Repair Kit, which restores relatively lower HP than the other types offers excessive heart points although the prices are really incorrect for any level.

We actually have had this suggestion before and it was shot down.
