Instead of only relying on the glyph, how about make every enemy affected by war cry become vulnerable for the duration of the war cry. We still wouldn’t get full up time on vulnerability on single target but will be much better than only three seconds per thirty second. Will make high tier nightmare dungeons a lot smoother for clearing mobs. If you think about it, it will make sense because enemy gets frightened by our manly roars, so they forgot how to defense there fore becomes vulnerable lol.
