Claiming that you don't need to use CC in Wotlk or time anything or that you're somehow defenseless serves no purpose but letting people know you don't know what you're talking about. The problem with MoP PvP stems from the fact that less equals more. More CC, more offensive cds, more defensive cds, more, more, more. When there's that much bloat in the game, proper usage of each one of those elements becomes far less impactful. When you're a walking bag of cooldowns that can't even scratch his anus without popping a cd, your games are less about fast reactions and more about staring at your cds and hoping they pop up before the enemy ones do so you can maybe have the audacity to try killing something
