It's not going to get removed, they've invested too much time into the spec. If they were going to remove it they wouldve done it already. Bringing back an old version of sv now would require a lot of effort for various reasons.
The melee hunter drama is a monument to their incompetence of game design decisions and basic understanding of their game. The game didn't need more melee and there's no inherent value to sv hunter other than ''being in melee with your pet''. Its just a generic weak melee spec that has never been popular untill this patch. It made hunter a 2spec class for many.
Remember that we couldve had a new cool creative/unique spec instead of them wasting time on this trash, such as dark ranger for example. That would be way more interesting than another shitty melee spec barely anyone took interest in for years.
