i don't think he understands what "timed exclusive" means. that aside, i've always been against locking out of content from the game, charging more of it and calling it "DLC". it's not DLC at all, you just download a "flag" that tells the game you paid up like a bitch.
i also hate "you can't have this, this and this unless you buy the game from "store X". dividing your player community is always a retarded idea.
I can understand where they're coming from on this. They needed to provide pre-order content as a limited edition and usually there is no way to get the limited edition stuff/features unless you pay extra later down the lines.
However, the decision to put in a gamemode as limited edition content seems stupid - should have just put in skins or some other pointless bullshit that makes kids buy the crap.
