DrK skill build question

Personally I'd say max stance. As stated above, it could very well be the difference between taking one hit or two. MW really isn't necessary considering everyone and their uncle has it; any time you'll need it during bossing at least one person will have it. Rush -I'd say it's a viable option. Personally I wish I'd maxed it rather than putting points into Aura. However, you're still forgetting Achilles. Undoubtedly one of the most under rated skills in the game. It is a highly helpful skill while bossing and makes for a great pot saver while training.

TL;DR? Finish off stance, max Achilles, and then max rush.
