Joined a leveling roulette in-progress and get to Vault with a salty samurai and red mage.
In Ser Grinnaux fight the samurai doesn't run, but
walks to the boss, doesn't even autoattack, just stands around and gets hit in the face by the straight-line attack that creates a black hole behind the player. And of course upon Faith Unyielding (or whatever it's called) she got knocked into the portal. I was like... well, I'm doing more dps than she, and I'm not gonna waste MP on an obvious leech.
We continue with the next corridor, the samurai more interested in blaming me for her death than actually contributing anything. The red mage isn't doing much better, so basically me and the tank carry their butts, until I decide I've had enough and would rather not deal with this crap past midnight. Both dps were mentors. Colour me surprised. </sarcasm>
