Are those raid frames part of your oUF, too? I have a question. Looks like you use oUF_DebuffHighlight, now, is that right? I'd possible consider going from Grid to oUF for my raid frames if oUF_DebuffHighlight can be configured to do everything GridRaidDebuff + GridCooldownText can do but I think that's just way too much to ask. Once Grid2 comes out I can get rid of Ace2, though, so, that'll be nice.
EDIT: I just noticed you listed Grid in your addon list. How did you get Grid to stand upright if that's Grid? I must do some digging around about that.
EDIT2: Figured it out. Just need to get the group numbers before the unit name like you have it, now.
