The overall 'hit' to your performance between using PitBull and agUF is probably so insignificant (especially if you're not using the raid frames) that it's not something I doubt very many would notice.
If I was unclear, then my apologies. I'm talking about grotesquely long play sessions that are definately edge case (although combinations of circumstances can speed this up to merely "profanely" long play sessions). Reloadui doesn't seem to clean up, though - a relog does. My voodoo explanation being that something is being allocated, tucked away, and never properly cleaned up.
In everyday usage, I don't think anyone would notice either. But I did, and it was either that, or SW_Stats, so.
Also, if you want to keep with the "Ace2" tradition, Violation is the lightweight minimal data equivalent of DamageMeters. It does, however, require that each user have it running for their data to be tracked.
That does sound like what I want (Player=damage, done!), with the small exception of everyone having to have it. I'm going to give Minnastats a try. At this point, I'm not interested in micromanaging or dissecting or anything. I just want to know, "Hey, $pug_warlock is doing less damage then my lacerate spam. FIRED."
