Truly think this couldn't be more correct,, true that "stole" is a strong word as all MMORPG do the same thing but 90% of stuff going into the expansion is coming from other games then blizzard's ideas for say "The Mists of Pandaria storyline is split into two - Main Story + Side Story" oh you don't mean like Current game SWTOR as done with class/side story or same as GW2 as announced and "All of the raids are all going to have three difficulties" - Normal, Heroic and Nightmare mayb, swear ive seen that lately. Just shameful to take all these ideas with almost none coming from blizzard then make a expansion outta it, at this point they are scraping the bottom of the barrel for ideas and nobody wants to pay for 2 MMORPG that offer the same experience.
Yes, can complain at me all you want but i really couldnt care less, this is my personal opinion ッ
