Pretty spot on with what holy melee needs doing to it, colosseum just needs to be made less clunky, or maybe just bring back merkbah but change it slightly, I miss merkbah.
-Faster 2h is a must tbh, unless you're using venom sting then it's hard to justify using a 2hander.
-Maybe adding flat defence to incarnation per hard point, could help with the pretty low defence overall without making it too strong.
