10.1.5 introduced a bundle of new icons as well as a facelift on the player’s action bars (for those that don’t rely on UI addons). This is purely subjective, of course, but for the most part, the new icons have been fine, such as the updated art on Repair, the cursor, etc…
Others, not so much. The quick access menus (by default on the bottom right corner) got new, very colorful icons compared to the previously monochrome, flat ones, but something about their new artwork feels… Toy-like, and very out of place in the game and in the rest of the very sleek UI that Dragonflight has run with, with the previous, flatter icons fitting in far better. A little more egregious, the smallest possible size of these menu icons is far too big, especially compared to the previous one.
The action bar changes I’m also not entirely sold on. There are a handful of new effects for when a spell is being channeled, when it procs, and when it has a charge cooling down, and their priorities seem almost reversed. The previously very noticeable flash of an ability proccing has been reduced to a very discreet glow on the spell icon, while the effect of a charge cooling down, a sweeping, radial effect on the icon, takes up far too much room for very little readability. Far more than just messing with muscle memory, they don’t behave the same or as expected.
Would it perhaps be possible to be able to choose between the previous effects/appearances of the menu and the current ones? It’s entirely possible that the action bar effects are simply something one can get used to eventually, but the design of these new icons, not so much.
