Whenever someone says "WoW Clone!!!!" I want to ask "do you know what that means?" A clone, in this context, would be something that delivers a near identical experience in every way, the feeling of the world, the story, game play, etc. FFXIV has some VERY distinct differences, just like the alleged WOW Clone Rift did, case in point, the soul system. At best we can call these games, siblings, cousins etc.

The Warframe your mention made me laugh as it proved my point. You say it is unique. Here is a comment from Gamezone"If you already enjoy games like Monster Hunter which require you to farm for items in order to craft better ones, Warframe follows that very same formula, except with much more satisfying and faster paced combat." So OMG it's a Monster Hunter Clone... oh wait no it's not.
