Couple weeks ago I bought Legion as I have with all expansions for WoW, and resubscribed for a month, however I have yet to log in and try any of it out. Last major release (WOD) I tried to log on after it released and took me over a week before I could take anymore than a step in the game the lag was so bad. Seems alot of people resubscribe for a month on expansion releases to try it out and maybe get back into the game.
Kinda like DoD:s, lots of good memories in that game which is why I go back to it from time to time.
