I thought it was fine before and after the 1% HC buff. The only thing I'd change about MCH is returning to Heated Shots, Spread Shot and Hot Shot granting 10 Heat instead of 5, and Quick Reload lowering Heat by 10. It was more fun and engaging to me. If we only get one AoE, too, I wish they'd give us back Grenado Shot and remove Spread Shot, even if they lowered GS's potency to be the same as SS now. It's a ranged job, I don't like having to go into melee range to line up a silly cone AoE.
