Haven't paid any attention to Legion news since it was announced.
How are Survival Hunters panning out?
I would suspect they'll always be marginally underpowered, just because of the shitshow if the 'best' hunter spec is melee and those hunter mains feel forced into it.
I think the actual gameplay of it is super fun. It's all about bursting Mongoose bites and then pooling for the nest burst. Plus you get reverse death grip which is super fun.
I think it does a good job of making you feel like 'melee with a pet' as well, probably moreso than unholy DK.
