It's merely a matter of preference. Both games have their ups and downs, and not everyone is looking for the same thing when they play an MMORPG. What originally drew me in to XIV was the fact that it was much more solo-friendly than XI was. I had played a free trial of WoW, but failed to make any sort of connection with the game and lost interest. When the beta became public for XIV, I only played for two hours before I knew i was in love, flaws and all.

I don't see why people can't just agree to disagree, and carry on and enjoy their games. Isn't having fun what games are about, anyways? :/

For the record, I probably have a slight dislike for WoW not because of the game itself, but for some of the players from that game. It's unfortunate, and I know I shouldn't let the actions of the few color my opinion of something like a game, but each time I try to be open about it, someone comes along and does nothing to prove me wrong. :<
