I don't understand why people would be so against an in-game parser. Even without one, it's somewhat easy to tell who's the weak link in the group after one wipe anyhow. If there's one that's only visible from the player's end that parses their own DPS only, at least they'd be able to diagnose what their problem is more easily. Hell, I'd love to have that for my MNK.

From this end I see more upsides than downsides, making a more clear-cut way of getting things done more efficiently...
