I used to play WoW ages ago and it's a very good game. The PvE in the end game (when you hit max level) was great, difficult, and well thought out. Playing in big raid groups of 16 people and working together to try and defeat dungeons was good fun. Yes, it was repetitive, but it was still very enjoyable. You can do a lot of PvP stuff too, in arenas and battlegrounds, although it's less natural and inbuilt into the game than eve even on a PvP server. If I wanted to play an MMORPG again it would definitely be WoW
