It was my understanding that Priests got Mind Seer at 75? I'm kind of looking forward to it as I'm 74 1/2 on my Priest. Though I havn't been back to the trainer at all haha.

I have been setting up ISBoxer so that I can use ClickBars to assign CC targets and mark and focus my CC. I think I would simple have a key that /stopcasting and reapplies all of my teams CC and perhaps a click button to apply individual CC.

3 or 4 Hex is still pretty decent. I highly doubt we will see Cataclysm requiring specific types of CC and I think you will see the restrictions on who can CC what being lowered so we dont see things like H MgT in TBC where in the beginning you really needed a rogue a mage a priest etc to have all the different mob types covered.

As someone else said this would perform poorly along side the Random Dungeon Finder and if they tried to add it into the queue system I imagine queues would be much longer.
