Does no one else use "Target of target"?

If your tank doesnt want to mark, then he/she is garbage. In case these things happen, you should be prepared to mark things yourself. As far as <tt> , I only use it when healing. You are probably using "target of target" on your rotation skills. Which isnt the best thing to do.

This is only really true early on. At end game, good tanks maintain aggro on everything at once so everyone can comfortably AOE without worrying about it. In this case, marking really is pointless. I only mark at end game if an add needs to die ASAP.
