I stopped playing almost a year ago, just a few months into MoP and didn't think I'd come back so I removed all my stuff.
Needless to say, I got convinced to start playing again when a bunch of my friends did.
DBM etc are obvious but I used to have probably 30 addons installed back then and it took a crapload of configuring and fiddeling around to make it look any good. I was hoping I could accomplish the same thing with fewer addons now that the expansion has been around for a while.
I should probably add that I'm no fan of addon-packs in general. I like crafting my own UI.
This is what I used to have:

Basically, I want similar (or better but that's subjective)
-Grid
-Nameplates
-Cooldown / ICD tracking
-Healthbars
-Adjustable castbars
-Anything else in there that's important but i've forgotten abount
Any help is appreciated!
