I moved to FFXIV.
I love raiding but 20m only for mythic killed my motivation to raid, I prefer smaller groups than big groups. FFXIV hard raids are for 8 players so that's great for me.
I enjoy having interesting things to do outside raiding. Currently in WoW it's only garrisons (no, I'm not interested in hunting treasures/garbage to sell) which is horribly boring. I liked the idea of garrisons but they were awfuly implemented. In FFXIV I can: craft (which is almost a game inside the game, crafting classes have their skills, gear, rotation,...), do dailies (every 10 days of dailies your reputation rank increases which unlocks more story for the best tribe, except for the Ixal which is every 4-5 days), collect random stuffs like Triple Triad cards or minion, mess with my house, complete those big side stories...
I also enjoy playing different classes without feeling that I'm being punished (or missing something). Thanks to the Job system in FFXIV I can have all classes on the same character so I can always progress keep progressing my character even if I'm playing a different class.
Oh and it'll be adding flying mounts, funny how one game removes it from relevant content and the other adds it hehe.
Now, what I think that WoW does better: bigger raids and better PvP. Everything else (in my opinion) FFXIV does better hence I moved to that game but I'm always reading about WoW here in MMO-Champion hoping that they'll improve the game.
