1. Currently yes. They have clearly made mistakes since HW launch but as long as they manage their original cadence and move forward from this point Im pretty hopeful for the game.

2. Just over 12 months.

3. Left WoW about a month into WoD. Honestly probably won't go back for Legion. They make it look impressive on paper but then again they did that for WoD too. Plus I value story and narrative and blizzard can't keep their story straight at all, and story is one thing that HW has knocked out of the park so far.
