For example, if i got that empower from lets say riposte, have a very small rapier riposte skill on the corner of the empower hud diagram. Its very confusing to know if you actually proced the buff or debuff since you also have healers, and such that are placing buffs on you as well.
Having your hp bar/stam bar very small beneath you character would also be amazing to have for PVP combat where things are done far faster then in PVE. the ability to move HUD like that would be great.
