Oops, yeah thanks for moving

Sure, I don't think the majority of RS3 players would care about a Wildy Revival suggestion. But I do think they would care if it were implemented. Personally I think catering to the wilderness would be the best thing for the overall health and growth of RS3. Players who don't care now would care once they saw the effects. It's just hard for many RS3 players to see it now because most of them started playing after the wilderness was already dead. Just my thoughts on that.
As far as Jagex caring goes, I think they care a bit more than that. They've been working on a few things to improve the wildy. Some of these projects are on hold at the moment (like the Bounty Hunter rework), but I think the fact that they do have plans for it shows that they care at least a little bit.
