Be careful condensing skills for a job that already has so few to begin with. MCH has this awkward issue of fat aswell beyond charges and laterals. you can remove quite a lot from MCH kit and still have the main gameplay intact that’s how shallow and uneventful it is.
Wildfire adding 50 heat would completely eliminate the point of Stabilizer being the same CD and revising it as a attack buff with removing WF would also not compromise the kit, or what’s left of it anyways. Good suggestions overall so long as they add somthing ontop of it to compliment it. Like if this was the only change plus that “yet another” aoe skill MCH would continue to be the most unambitious job in the game
