As a hurler, the other stances don't do much for me. Prior to the recent updates I always ran griffin, but that's almost pointless now with the elimination of vocal stress. Tortoise stance really shines when you combine it with the skill that let's you block for other people. That's usually the only time I run it, when I'm guarding someone else. It's very effective in that regard.
I don't use Lich. If you want to do business with me, contact me via PM, IG, or on AIM. Or maybe use smoke signals. Don't like it, get off of my lawn.
