Flamethrower could generate heat but it would remain an AFK button.

By the way, this is the 4th expansion in a row where MCH is underwhelming at the beginning of the expansion!
HW had too little damage and long cooldowns.
SB had overheat at 10% which was a DPS loss.
ShB all ranged could be replaced by a barely good BLM.
EW the just is simply underwhelming and offers no value.

I guess the curse keep on living!
