I did try to play it out of interest in the past, but I stopped due to being more interested in other games.
Though WoW, is a pretty good game, there are a number of other mmorpgs out there that give it a run for its money.
To be honest I've stopped playing WoW years ago. I didn't like what Blizzard has done with the game. I remember meeting stones right outside every instance - that was the time when wow community was at its best
I stopped playing WoW, because late game have no sense for me. There are many other games that have so much more interesting endgame
