How many people are keyed for heroic mechanar? You need revered with Sha'tar to get the key. Heroic mechanar is an easy way to get badges of justice. Both gatekeeper minibosses and the first main boss drop badges, and they are all easy to kill. The second boss is a royal bitch and most groups skip him. The final boss is a good bonus if you have an appropriate group (need 3 aoe fear classes ideally, like warrior + priest + warlock), and he doesn't take long to get to after killing first boss.
