If there's something to complain besides the barb bug, I think the way settings are handled is very unpractical and clumsy compared to the old checkboxes. It's infuriating to type text into pop-ups compared to just clicking your mouse a few times.
Also a user is going to know which ubers he's done/is able to do at any given time, but he might not know the precise +max skills from those ubers/items without checking up on docs.
