Level 63 Wizard here...
My UI preferences are 1) Personal and 2) Wizard related (flamers take note)
1 - As others have noted a Target/Casting combo is a must.
2 - Prominent and Oversized Player Health bar. Wizards (and all casters) are wimps and can NOT take much damage. By have a big and promenent Health bar I have been able to save myself many times when I would have tried to fight on with a smaller and less effective health bar.
3 - Prominent and Oversized Mana bar. Wizards live, die, breath, sleep, eat, run, walk (you get the idea) on MANA. It is our most important battle stat. Therefore, I wanna see the mana. Again, wimpy, hidden or obscured mana bars are a nogo for a wizzy. We want em big and prominent in the Player window!
4 - Small, efficient spell book. Wizards are CONSTANTLY meming spells. We need to get to TLs, Nukes, AEs, you name it. And we need to remem them quickly and easily. I can't tell you how much I like the new Spell Meming Groups added in the last patch! But, for a UI Spellbook I want it small and uncluttered - I don't want to have to move the mouse all over a bunch of graphics just to get to a TL. I want the borders on the spellbook to be minimal so that I can position it right next to my casting gems for quick meming.
5 - Casting Gems need to include the text of the spell!!!! With dozens and dozens of spells that all have the same gem graphic (TLs for instance) We need to know at a glance which ones are memed. I hate having to move my mouse over the spell gems and hold the ALT key just to see what is memed, bad news. Having the text of the spell is crucial for casters. I personally like to have the numbers of the slots there also. In the heat of battle I may have forgotten if I put that AE spell in slot 6 or slot 7. I can't afford the time wasted to "count" down the gems to figure it out. With the numbers right next to the spell (and big ones I like) it is a quick glance to know that AE is in Slot 6.
6 - Streamlined Containers!!!!! Casters are always moving gear on and off for resists, cha gear, eb items etc. Small, streamlined containers can make this much easier and quicker. Casters also tend to be more tradeskill oriented and tradeskillers always appreciate a small container mod, so that we can slide em all together on the screen. I love to have my 8 main slots open and all my 16 bank slots open and now even my 2 shared slots open. All at the same time! That is 26 containers! Not to mention my Inventory displayed too! You had better have a small container graphic to make me happy!
7 - Here are some things that wizards do NOT care too much about. Group boxes - bah, we solo most of the time, LOL. Seriously, we do not buff, we do not heal, we do not quicken/kei/sow or rez. About the only time we use the group box is to do an occasional invis! Pet Boxs - bah, the only pets wizards get are lame and uncontrollable. All I need to know is if it is alive or dead and I can see that in my buff bar - get rid of the pet window for wizzies. Friends Window - bah, Wizzies are loners, we have no friends, LOL.
Again, these are just my personal comments and they are strictly WIZARD related. I realize other classes and even other wizzies may have other opinions. These are mine
