Some ideas...
  • Dismantle -> reduce cooldown to 60s (now: 90s)
  • Cooldown -> reduce Heat by 15 (now: 25)
  • Rook Overdrive -> Rook cannot deployed for 30s (now: all turrets cannot deployed)
  • Bishop Overdrive -> Bishop cannot deployed for 30s (now: all turrets cannot deployed)
  • Barrel Stabilizer -> Can be executed during Overheat (now: cannot be executed during Overheat)

I have no idea how to fix Flamethrower and Overheat in general.
