I'm going to play both - sssort of. My PvE fun is going to move over to Classic for sure. On retail I might still play PvP because of a friend of mine but unless I see much improvement over BfA: I'm not buying any future expansions. I'm just gonna use retail at that point to RP because that's the biggest reason I play WoW, but RPing every day isn't an option (which is why I need PvE stuff to do).
