Honestly, I loathed Survival in Legion. I was super pumped at the idea of Survival Hunters being a Melee Hunter but couldn’t really get into how complex and clunky they were. BFA’s are in a lot more enjoyable place, for me personally, and I really like them.
Honestly, I really would hate to see Melee Survival removed. I would rather see fourth specs become a thing so that both styles can co-exist together somehow.
I played a bit of Survival Hunter in MoP and it was by far my favorite spec for Hunter back then so I do get the desire to see it back. Surely its possible to reach a happy medium with both sides winning by having both formats exist.
Just my two cents.
