oUF is on the border of insanity for me — it requires you to fiddle with .lua or download a ton of “support” mods — also called oUF something or other — in order to customize it with any kind of proficieny.
However, if by chance you stumble across a pre-configured oUF mod that you like, most of the guesswork is taken care of for you, and hopefully, that means minimum fiddling for you.
I’m currently trying out oUF: Cliche. I haven’t quite decided if I’ll keep it yet. Out of the box the unit frames are humongous, so I had to manually slide my UI scale down a bit — which of course makes my Blizzard UI elementals (character sheet, etc.) look kinda sickly and small.
So far, I’ve had to manually move the raid frames since they’re obviously positioned for a dps, not a healer, being located in the upper left hand corner of the screen.
Currently, the author is listing it in beta, and I’m gonna give it a go for a week or so and see how I like it.
