After some holiday travelling I've finally taken the step... and respecced my warrior to prot. Yes, it's true. And also it's more fun than I thought! Thanks to Shield Slam and Devastate it's not all that lame as I initially thought. I haven't tried out tanking with it yet, but killing works ok. Way faster than killing single mobs with my protadin anyway -_-
Speaking of which, only one more level for Outlands with it! It'd be my fifth char in Outlands then.
