I find this comment interesting. I don't think that easier heroics would solve the problem. Case in point: my tanking warrior is currently 79 and is blasting through LK normals. These dungeons are easy, nobody could call them anything else. Because it's easy, I had 3 runs of HoL yesterday where a hunter (different hunter each time) would run ahead and pull packs, not misdirect them onto me or anything just pull them and have his pet tank them. Because he knows he's not going to die as a result. I was pulling like a madwoman already because if you take the time to type 'Hi guys! Let me know when you're ready!' you get either silence or 'gogo ffs noob'. One literally ran from the golem boss through the gauntlet room, brought all of them to life at once, grabbed the two packs of elementals from the next room and proceeded to tank them. That is not fun for me as a tank. That doesn't allow me to do what I enjoy doing, which is set the pace through the instance and control the mobs.

My point is that the LK dungeons were just the right level of difficulty. You could go into any of them with any PuG group and have a very decent chance of success and be able to collect your badges. If DPS chose to be silly and irresponsible, it didn't always result in a wipe. They didn't require 2 to 3 hours of grief like the Cata dungeons. As a tank, you still have the ability to set the pace in a LK dungeon - don't let an idiot ruin it for you. Also, you're going to love running Cata dungeons if you enjoy being in the driver's seat as a tank.
