Built-in Parsers

[NintenPyjak64]

I'd like to ask a hypothetical question to the anti-parser people

You're doing O3S, you have a NIN, MNK, RDM and MCH for DPS, and you fail a DPS check 3 times in a row (ignoring tank and healer DPS, let's say it's the White Flame). Somebody you're playing with is running ACT and notices the RDM has considerably lower DPS and higher HPS then usual, and are the only person who has 1 or 2 deaths per attempt. Checking the abilities used shows the RDM is frequently casting Vercure, Jolt 2 (while procs are available) And unenchanted melee attacks.

You and other party members offer advice but it falls on deaf ears. Another failed DPS check and people are starting to get angry

You are the party leader of this team, what would you do? What do you think is fair? Does the RDM's enjoyment of how they play justify the growing frustration of the other party members?

EDIT: The party is a late phase learning party or a weekly kill party. NOT a fresh learning party
