Hi! When playing my Gladiator and managing defensive abilities I find that determining what ability is fading when can be problematic. Sentinel, Defender, Rampart, and Obsess all share the exact same buff icon. I think that if their buff icons were replaced with the ability icon it would be much easier to tell at a glance what you have active and what has faded.

Other examples of shared icons are (I think) Raging Strike, Ferocity, and Discerning Eye.

Oh, on a somewhat related note: It'd be nice if Guard had a buff duration icon so you could prepare for it to fade.
