"I am rolling a Worgen warrior to be my tank."

Word of advise then. Im not sure has they fixed after betas end but I really really must bring this up public as I can (the doom is comi-.. oh right not that subject)

I'm not rolling one myself but I'm pretty neutral to them so far so this is not hateful message, just my critic towards them from experience of beta.

First of all the problems I had with worgen are these:
-Sniffing. Yes, they DO sniff almost ALL the freaking time. No, you cannot stop it on form. When you level prepare to hear a lot of "snor snor snor snor" "snif snif snif". http://www.youtube.com/watch?v=IZsNiQpnDOc

-You will drive yourself insane if you want to be tank with worgen. They go "WOOOOOF!!!" everytime they get hit. Its loud, its painful to ears and just.. gosh. Its just like getting fall damage on elekk after being totally silent for hours with headphones, it was THAT loud. Also it feels uneasy for certain reasons. But you wont hear them in loud instances or raids.

-Running wild looks like its taken from cheap pron movie. Thats gonna be so joked about. Prepare for "funny guis" dancing behind you while "mounted"

Otherwise go for it. They seem really fun and savage.
