LFR requires communication? How the hell will that work out? Everyone needs to be in vent? Because typing in the middle of a raid is not gonna work.
Player 1: Hey, stop standing in the fire!
Player 1: Whoops.. fire appeared below my feet while I was typing and killed me
Think it's time to stick to normal raids :P You just can't expect coordination from the average donald in a pug. Rarely do they even understand what basic features in the game means.
