The whole UI seems to me like something that should be more fit for a small screen device, where touch gestures swipe stuff around and you just can't put a ton of stuff on the screen.
It's funny you say this because gamesas took influence from Apple on their UI design.
I think the menu is pretty easy to scroll in and out of when using the anolog stick. And you can scroll through the different trees quite easily when using the stick, too (which I didn't originally do).
I think the worst part of the UI is the skills trees. It's like they've degressed in design; you should be able to view your talent trees in its entirety on the full screen, and quickly view each perk to plan your way through. Scrolling up some huge line is pointless; players want to plan theirs character's progression over a long period of time, but want to view the different steps they can take in a quick manner between levels, or take longer if they want.
gamesas, you make good games but what the [censored], do you even think sometimes? I sometimes wonder if any of their dev team even play RPGs in their spare time, because this seems like one of the most obvious flaws in their game. What do RPG gamers favour, a glossy skills tree that looks like the night sky, or something very practical?
You decide.
