As someone who uses controller on PC...they should just suck less.
I know Kotaku is more of a sex blog than a gaming site, but anyone who actually knows raids from any other videogame knows that the first 48 hours are typically only when the best coordinated groups beat raids. Hell longer sometimes. They're not meant to be easy, if they were they might as well not be called a raid. Most casual gamers expect to queue into a pub game with their shit gear and breeze through like clockwork. Ain't how it works. Most of the top and most serious players are probably on PC, that's not really surprising.
