For a long time I was running with a purple UI, partly because it’s my favourite colour, and partly because – hey, Warlock colour! But since I’m now playing my Paladin a lot, I decided that she needed her own UI. (Démonique gets to keep her purple goodness of course.)
I use an addon called Btex to add bottom textures, and it’s quite easy to make your own textures for it. I decided to go for something golden-ish for the Paladin.
I think it turned out rather nicely, and my Paladin doesn’t feel as much of a second choice after the Warlock since she now has her own texture. Been considering making new ones – one for each class, but might be a slight overkill!
If you’re interested in the addon Btex, you can download it here.
If you want to use any of my bottom textures, feel free to grab them. Depending on your resolution, you may need to edit the width in Btex (in-game) to put the map in the correct place. On mine I have to make it 490 to get the map where I want it (default is 512).
