I agree with those proposed changes too. The changes made this expansion were good but I think more is need especially to dispell the current attitude towards the class. Just the other day I offered to off tank something and got laughed at but I know I could have done a good job at it. It's that attitude more than the state of the class that bothers me.
I'm hoping it will get better when I fill in some more aa too. As for Tranquil Vision, half the time I find I can't even cast it on another tank because their buffs overwrite it or something.
