Yea. In SL I quit mid-expansion. Never touch BFA and came back for SL and shortly after 9.1 quit again. There are too many things you HAVE TO DO. Is not fun. I am playing a game I am doing chores. There are dailies you need to do with your conveants, grind at least 10 m+ 15 dungeons for upgrades, complete at least 10 raid boss at the highest difficulty you can do and then Torghast every week, and do the weekly at the vault. If you don't do all of these task or miss a few weeks coz you know people have lives outside of WOW say goodbye till next patch coz you will never catch up.
Then there is the META FOTM or class not balance. Is nothing people need to worry about till you are doing m +20 or mythic but yet a lot of casual and group founder somehow things you have to play the META for a +15 or even a +5 so you get rejected for not playing a META class. Then there is too many class/spec/gameplay that needs to balance but it will never be. You have PvP, Arena, BG, raids, m+ they all require different things from a class. I want to try Dragonflgiht but so far reading the blue post form blizzard I think it will just be another let down.
