Funny, I feel the same way about Shusio, Sophus, Xelltrix... they all make me cry daily...
Seriously jerk players like that **** me off too, I'd rather not be told how to play my job, but if I'm making a mistake, letting me know what adjustments I should make is never a problem. Just don't keep telling me to Provoke... I know better than you when it's up and down...
What I find is funny is when people tell you how to play your job, but doesn't know their own, for example, the White Mage who will never Curaga+Divine Seal between gob fights in the Dune when they have near to full mana and everyone is in the orange... of course that guy had other problems, while telling the Warrior every fifteen seconds that they need to Provoke... (how they were pulling so much hate without casting any heals is beyond me... also saw one Protect spell, no bar spells, and not a single debuff... hell, I rarely had a Cure thrown on me except from the Dancer).
The point is, that one of the great ways to relieve stress is to talk and deride those that annoy you. I'm sure that if they read this, the dude from last night will know exactly what I'm talking about.
