It just seems cumbersome. I mean look at all that screen real-estate used to configure a single skill. I think it would have been better to arrange the UI to allow the configuration of all the skills in 1 window. Sure it will be cluttery, but more powerful in the long run. Hell, the last 1/3rd of the screen is almost useless. Then again, I guess it shows off the artwork of each skill/rune![]()
I read somewhere that blizz changed the skill UI and made it more intrusive because people were running around with the screen open and just changing the skills on the fly while they played.
Blizz didn't want this, so they made it so big that it blocks your view and very hard to play with the screen open.
