I must say I was lucky with leveling my bard (still have to run few libraries) and didn't get really much wipes... but I agree lot of times dps forget about the sable price in the aery, or don't know where to run in the vault (I am still psychologically preparing to try heal vault; as I am an average healer). I have no problems dodging in the vault. When you run it several times there is a patern; I start failing those when I am tired and run it to many times, which means I am taking a break from it.

But I noticed lot of times when there is a wipe is because the mechanics aren't followed or simply ignored.
