I'll join the chorus and say so:

1) Rework overheat! It's boring and the usefulness is only marginal and prone to error. Best without it.

2) Rework Flamethrower! For our lv70 skill we'd expect something BIG. I'm not even talking about the bugs that need fixing.

They need to shove in more debuff utility in the MCH job or just plainly buff it's dmg to be on par with the other dps!
