The game is pretty unbalanced between types. Heat is stronger than physical, and energy is either OP or weak af depending on whether or not the energy mech has dual val.
We don’t need some elaborate change to balance, just a few small tweaks
A simple fix would be to
Nerf val from 189 drain down to 145.
Cut energy and physical wep heat cost in half.
Give heat drones energy cost of 1
Reduce resistance drain done by phy weps and drone by 5 per wep
