I'm running a DK Breton Magic DPS/Heal with a flame staff and a resto (of course, lol) staff and I've found that sometimes no matter how hard I try I can't switch weapons. I'm not stunned or anything, it's like there's just no response from the UI. It seems to happen in the middle of a more intense fight, where the lack of using my heals causes me to die, so I really don't pay attention to my stam bar. Does switching weapons use stam as a resource? With my attribute points I went mostly MP with only 10 HP (for a bit of a HP pool) and 5 stam. Should I put a few more in stam, or is something else happening?
