Unlike alot of people who use this miniscule kind of UI, i don't and i find it to work perfectly well Sunny. It makes it so i can see my rotation at all times, while still looking at the boss and what is going on. When it comes to UI, i feel that if you can see what's going on without a problem and do what your supposed to do it's a good UI
Its the unit frames and oversized role icons that hurt my feelings/eyes, but other than that it's ok.
Oversized role icons, how can that hurt your eyes? The thing with this UI is that it fits me and all procs, hots and so on is in the middle of the screen, easy to keep track of, but not in the way of anything
Its more a case of removing the things you don't need so that you can see the important stuff more clearly. But each to his own.
I deem my health bar, rage and cooldowns to be the most important things to me, so they are big and staring me in the face... everything else gets minimized.
I pledge allegiance to the UI of Sleiverts, and to the horrors for which it stands, one abomination such like Parrot, big role icons, with bad positioning and out of proportion elements for all!
