When MoP first went live this just wasn't true. It took them changing rep requirements on the different items, adding in increased rep modifiers and a new set of gear that was extremely easy to get. Now sure if you were a top 1% raider then it was not mandatory at all, maybe not even needed for a single item. The gating at the start of MoP was horrible. They did it with gear, rep to get into different daily zones and in the 3 raids. It was like the worst of all gating in the past smashed together for the superstorm clusterfuck of gating.
