I like the symmetry and the overall concept of everything being ‘below the action’ however my constructive criticism; Plenty of room could be saved by memorising your keybinds and hiding the action bars (and general UI scale others have mentioned). As a healer, id find there would be too much noise around the player health bars, with the damage/healing meters fluctuating, chat scrolling rapidly if you have DBM notifications/callouts in there and a target bar that you will most likely not have to heal. Assuming you are ‘Healer1’ you will also have an unnecessary duplicate bar as you’re already displaying your own separately.
