UPDATE: Went back to my Warrior, and playing PvP, so Arena frames are disabled because I replaced with Gladius, and corrected the mess on Boss Frames.
I've made this UI for my Retribution Paladin, but I believe It can be used with any class, but since the focus was not on casting, casters might need to adjust the cast bar etc.
I'm using 1366x768 resolution, but with scale, might fit to any screen, haven't tried, sorry.
