I tried buffalo2, and it bugged out :( and i thought buffalo wasn't working anymore? lol, but apparently it is. SBF is very nice, but it just doesen't have an option like in Elp's for a shorthand of the buff name. i almost always forget to rebuff with certain things in my raids, and just recently got the addon SimpleSelfRebuff (its super simple and freakin awesome) but raid buffing isn't included, and PuntFu has to be configured too much for me to pay attention to lol.
im using bongos for my bars (theres a screen a few posts up) and the srenity and things is still too cluttered for me lol.
It's actually dark blue by default. There's a lot of mods out there that customize the Shaman class color though, because a fairly large amount of people find it tricky to distinguish the Shaman's dark blue from the Warlock's dark purple or Mage's Blue.
I've personally changed my Shaman class color back to the teal it was before it got changed to dark blue.
