Post-2.1 Classes

I'm not really an expert so looking at the changelog of the update I can't really tell which classes got f*cked and which are still fine. I'm also not very rich but I wanna buy mythics and have a fairly maxed class but I don't want those emeralds to go to waste on a bad class.
Which class should I invest my emeralds in for a high budget build?
I like archer and maybe warrior too but I'm not sure what's happening with them.
I know there isn't a single best class for everything but let's say for lootrunning, raids and whatever else there's to do in this game.

 

Honestly for raids Shaman, for lootruns Warrior, though for some raids like NOL you need warrior

 

is archer good for anything expect like maybe tna?

 

archer does great on pretty much every raid, for world events only trapper seems to be enjoyable

 

archer is also really good for raids too

 

Archer is trash for everything :(
