Swipe will usually get replaced by Brual Slash talent, and if youre worried feral has bad aoe/cleave, that is unfortunately true.
However, feral rocks at almost everything else. It’s just great. I don’t know about soloing legion specific dungeons/raids but I gotta imagine it’s possible. If not you can just go bear and nothing will give you a problem.
Causal pvp feral feels like a God. Running around korthia can just take any 1v1 and most 2v1s… and if you get jumped by several you at least have a chance to survive and run.
Covenants you want to be necrolord or night fae. Either one is very powerful. For 9.2 it’s probably going to side more towards night fae unless the necrolord legendary gets a redesign.
