That or some people just prefer WoW to Wildstar. I enjoy all those things, I didn't play Wildstar, because I didn't enjoy the skill shot only system (if you had any type of lag, good luck on hitting anything.) Wildstar had serious issues and that's the reason it failed miserably.
Don't assume that's true at all, Nostralius which was a Vanilla server got peak population of 10-15k per day on the server. A lot of people refused to play there as they didn't like to put the effort in and get their character rolled back, or deleted when Blizzard shutdown the server. You'll see a much different outlook on how many do enjoy that style of game, when Blizzard is fully supporting the community.
