well, definitely alot of people will go for DK. I agree that more DK means more tanks.. cause they can be casters/cc too. its a hero class remember? summoning and raising the dead to help.. well. its cool... but where does DK stands when it comes to end game of level 80s, we dont know yet.

As for me, I will keep my tankadin up .. not changing alts.. firstly, i dont have an alt that is level 70, secondly.. I think all classes will be buffed/nerfed equally and they will be equally nice to go through the contents in Northend..
