Had to skip over the current posts to share a similar experience. (I'll read the others after I promise.;; )
I also did roulette (just the low level one) recently. Skipped cutscene, popped Protect and waited for the PLD tank to move. Standard stuff. But then he just... stood there. He moved after a few seconds and proceeds to attack. No shield lob, no flash--so naturally things started to come for me. The NIN and BRD told him nicely he should use Flash when he can (and in proximity of the mobs). We move on, he uses Flash out of sight of the mobs, still hasn't used shield lob.. I figured he's either lagging or he's pretty new, so I just /cheered him on when the NIN and BRD scolded(?) him again. Plus he wasn't talking at all so maaaybe he was feeling embarrassed?
Bottomline is, I gave him the benefit of the doubt all throughout the dungeon even if he still used Flash in front of walls and inanimate objects. The other two left without another word and I was left with this guy. The only thing he said was "Have what do".
And then he left the instance.
What?
(also i'm sorry i don't have anything to vent?? is this already off-topic??)
