I think it's ok in general and will probably grow to like it a lot but..
Player names couldn't possibly suck worse, now. The font is way too bold and having the guild name on a seperate line just makes the name too bloody huge. I can go to a ssra raid with 50 people, have all models on with spell effects at high and get no slow down, but pc names on in bazaar kills my poor PC now.
The very bottom line of text in the chat window cuts off the bottoms of letters like g, y etc etc. Yeah this bugs me :\
Spell icons are nice looking but haven't you ever had to scramble to swap out spells real fast before? Good luck doing that until your'e used to the new icons and spell book
Having to move my pointer into the chat window every time I want to use my scroll wheel is dumb!!! Yeah most people will have multiple windows now, but why can't it default the scroll wheel to the main chat window if you're not pointing to any?
What's the point of the big black square of nothing in the inventory window? Just to auto equip? The entire inventory window centers around this big blob of nothing.
Inventory window no longer shows you how many aaxp points you have saved up, you have to click the alt advancement button to see. Bah.
I only played aruond with it for a half hour or so since it took me around 5 hours just to get online, so I'm sure I'll have other things to pick on later
