If your going by that logic, any game with the word Warrior, Theif, Mage, Monk all came from FF1.. Meaning that all they are doing is using names from previous games. The words aren't copyrighted, there is only so much inginuity for character names. Well hell, I could say that Lich King came from FFT simply because it was a Summon.

Now, Anywho, WOTLK looks like it will be another amazing expansion. I play WoW and WoW:BC for awhile, but never got into it, Although I liked the gameplay and the Blood Elves (Horde FTW). My computer couldn't handle it or I would still be playing it. WOTLK with be awesome none the less when it is finally released.
