I'll wager that Dual-Speccing will be yet another source of loot angst. *joy*

Whenever it becomes a reality (and I'm not holding my breath on it) I'll dual-spec Healadin/Tankadin. Until then I'll stick with Healing.

One thing I've noticed about PUGs as of late is that the ease of going through the dungeons in Wrath has made everyone lazy. No one wants to CC because they can blow through anything in their high-end gear from BC. Once you get to level 80 dungeons and heroics though that doesn't work out so well - tanks can't hold threat as easily, healers can't heal through everything and DPS can't down the mobs fast enough. Folks need to get back in the habit of following kill order, watching threat and using CC. Once they do it'll be a better environment for new Tanks to get their feet wet.

As another poster pointed out, you have to enjoy tanking to do it regularly and you have to do it regularly to do it well...the flip side is that no matter how good a tank you are the group you run with has to cooperate or you're just racking up a huge repair bill.
