So the current situation with WoW is if you put up an absorb shield on a target it displays on their health bars.
This would be a very nice addition were it not for the unfitting graphic it comes with.... Since cataclysm, a blue and white striped glowing bar signifies that you have and absorb shield on - this feels more like it belongs into sci-fi than fantasy really - it looks like some kind of force-field generator on your health bar.
When I first saw this thing on my healthbar in 2010 Cata I genuinely thought some thing was bugged. Then I found out this shitty display is the absorb shield. It just looks fucking disgusting, like an unfinished texture.
