You do realize WOW stole most of its ideas from other games too, right?
WOW didn't invent the tank, dps, healer.
WOW didn't invent grouping, crafting, guilds, etc.
I love how crafting is in this game, I can make useful stuff while leveling actually!!!
I LOVE AREA LOOTING!!!!! How long is it going to take WOW to "create" that idea?
