That's the funny thing about inspiration: you never really know when it's going to hit.
I was playing Wizard101 with my kids last night. (I think I've mentioned that I play that on occasion before.) It's a very whimsical game. The combat speed is good for my 5 and 7 year olds. At any rate, it's a very minimalistic UI. As you can see from the Screen Shot here on the right, there's really not much to it. You have your basic health and mana in the lower left corner. You have your xp bar in the bottom center. Chat and interaction buttons are found in the upper left. A compass and the options button (that also opens up all spellbooks and gear and such) is in the bottom right. (This picture is actually a little old since they've added your various "hearthstones" near the compass.) And I have no idea what it is in the upper right corner; mine is a link to go buy the game or get a membership. (We've always just bought areas when we're ready to go to the next area.)
So, it may not be fair because the combat system is completely different, but after putting the kids to bed, I logged on Wow and started to compare. Holy crap I have a lot of buttons! With 12 standard ones, then another 24 laid across the entire screen just above those, and then another 24 on the right side... And with my shaman (as with my mage for that matter) every single one of those is taken up with something important. Which is actually quite humerous since I know I'm not casting 60 spells!
So, let's focus on the shaman for a second. 3.2 will take care of a lot of these problems since I have a lot of extra buttons just in case I need some random totem. Then, I'm not really sure I need all 3 shock spells. (Well, technically there are 4.) Especially when I'm in Resto (which is only when I'm in a group in an instance).
I know I've put off completely redoing my UI because on my standard screen (non-wide) there's just not a lot of real estate, but really... that's exactly the reason why I should do this.
I really need to go look up my blogging friends' posts. I know I've seen a couple people that have had some great approaches to fixing the UI. Then again... maybe I can put it off so that 3.2 doesn't break all my add-ons. lol.
