I've come back to WoW a couple times since MoP. Each and every time, without fail, I grab this UI. I'm very picky about my WoW UI for some reason and this scratches all the itches, ubiquitous design, feature-rich, customizable, etc. Never disappointed by it and I have a feeling I'll keep using it every time I come back. If I weren't broke, I'd donate a bunch of money out of appreciation.
