No they haven't. We've gotten an "expansion" which is a content patch essentially, which is free in WoW. They've added new daily zones, a new raid, a new battleground, new tier of gear and a ton of mounts in the with the thunder king patch up to now.
SWTOR just recolors armor and mounts and brings in nightmare mode content as "new" content. Claims the next patch will be "exciting" and then it's just the same old crap we've done before. Hell even the "expansion" launched with THE SAME DUNGEONS WE ALREADY HAVE!
How anyone can sit there and say SWTOR puts out more content then wow is just a fool and has a blind hatred for a superior game.
The only reason anyone plays this game is because it's star wars, not because it's a good game.
