pretty much, they're not that useful in DF... odds are you won't even see those people again anyways.
although, I do wish they were part of the stock UI.. or at least as ubiquitous as they are in WoW... the average dps player in WoW puts out numbers a lot closer to their theoretical max than the average dps player in ffxiv does, and i have to think that parsers being so prevalent has something to do with it.
