I like most of the suggestions, except:
-Even though I like getting rid of warfare damage bonus, the new bonus you suggest is bad (it's like nerfed retribution which is bad itself)
-Hunter giving extra range might be used to cheese encounters shooting them from unreachable places
-I like uber incarnate to stay in the game, although it messes up summoner power scaling. Maybe keep it as a higher level skillbook (potentially source) instead? Also, summoning gives 10% already even if tooltip says 5%
-Scoundrel only giving movement feels bit weird to me, it can be powerful with the higher bonus for sure, but I'd rather have it give something useful for combat too than being a pretty niche and potentially OP skill for some uber kite builds
-I don't think LW nerf is enough, but that doesn't bother me too much cause you can avoid it pretty easily
