I think a personal parser is a great idea, but I think the median 80% of players would still put up...well, let's just say, less than mediocre numbers (I'm being pretty generous when I say "mediocre" too, my BLM doing thunder and blizzard 1 should not be out-dps'ing other BLMs...). I think a group parser is extremely important for end game play however, and especially given the current state of Savage design, is really the only way to improve and progress.

tl;dr: I'm all for personal parsers, but group parsers should exist for content where it's necessary to progress.
