I think that the current skilltab UI is a pretty big downgrade from what they used to have. They had a much better UI in beta before launch but then they switched it to the current consolesque version you see today. You know those arbitrary groups of skills like "Tactics" and "Rage"? Those never used to exist (so you didn't have to sidescroll through pages of random skills to find the one you want). Despite the massive outcry in beta they still rolled with the current UI (+the hidden elective mode).
