Not really a facepalm moment, as there's some debate whether this is a good idea or not. I've mained WAR since beta. My cross-class skills have always been Flash, Provoke, Convalescence, Featherfoot, and Internal Release (occasionally switched out for Awareness). On a whim, I switched out Internal Release for Haymaker, thinking that I might get some use out of it when there's actually something hitting me. Wow, what a lifesaver. It doesn't work on everything, but cutting a mob's dps in half for 12 seconds is amazing.
