I very much enjoyed Survival in Legion. It was great to play and a lot of fun, although it was middle tier DPS. Without a proper artifact weapon in BfA it just didn't feel right anymore, the gameplay was still good. The same in Shadowlands.
I think it's by far the most complex and fun Hunter spec, unfortunately it's good such a bad reputation that many won't even try it out. I love the trap / explosives playstyle and I never understood the issues some have with a melee hunter spec.
