I wanna ask, if you guys have been reading what the stats the abilities rely on? I noticed during my muscle warrior playthrough, every ability I obtained is scaled by basic attack stat alone, not special attack. After investing a lot more into it, I died less significantly. Some stats are still useful like vitality or speed, but I mostly noticed some like special attack on muscle build is unnecessary. When looking at your skill choice , try to looking for the stat next to it for best value out of it. I hope this helps!!
