I did (fairly) hardcore raiding with the Eclipse UI. You can make UIs for raiding very minimal and also effective if you really commit to making a UI for just one class and raid role. And by raid role I mean more than just the general tank/healer/dps role, I mean the exact moment-to-moment role that you as a person in your specific raid group are fulfilling. Also, how you use raid warnings can vary a lot depending on your specific raid and tactics and things.
As such, I deliberately trimmed back some of the raid warnings and bars and things before "publishing" those UIs. I figured people could (and should) make those additions themselves.
I never added a bar for Celestial Alignment because it triggers Nature's Grace and has the exact same duration. I used the Nature's Grace bar as it's timer. One less timer, woohoo! :-)
Nice UI!
