Wouldn't it be better to get rid of flash and put awareness and keep second wind? For single target bosses I mean. I mean you might want to flash to keep enmity when pacified, or put flash on your rotation to conserve TP. But other than those two uses , if you're not picking up adds ( and even then should use storm cyclone and an overpower once in a while) I think flash is nearly useless, and would prefer to boot that for awareness instead of second wind. Second wind can crit for a good 1.1k or so, and it can be a nice little cushion sometimes. It really isn't much at all but with a warrior that has str points it can be fairly handy.
