H1Z1, cheap game, you'll have countless hours of fun - even when getting shit on from hackers. Not sure your type of play, but there is both survival and battle royales. I've not personally tried the survival part, too much work it seems like so I stick to BRs, almost 600 hours logged and still going.

So I'm thinking either H1Z1, Guildwars 2, or Tera, can't decide...

tera

gw2 is like tera but less polished combat and more micro transactions

I'm burnt out of wow since 2 weeks after wod came out

Quit wow in september of 2015. Came back early Jan 2016, literally had nothing to do so unsubbed again. I might give Legion a try but dont know tbh. Just playing some casual single player D2 for lols atm.

runescape

Depens, I personally only play this together with friends, kinda feels bored alone.
Anyways I went from wow to CSGO, #NoRegrets
