Never got kicked either. My first win at Titan Ex, my party did think about it when they realized it was my first win (the achievement notice kind of helps) because it was supposed to be a "farming party" ( and we did farm him a bit in the end, winning 5 times in 45 minutes ), but when I told them "you never actually REQUIRED in PF that I had won previously so you can't say I lied about anything" and explained to them that I did had experience in the fight, they aknowledged I was far from a nuisance and let me stay (I suppose being one of the tanks and having my co-tank saying "you're doing even better than me" helps, too.).

Otherwise, I'm generally considered a good tank (which I'm playing over 95% of the time even if all combat classes are at 50) and while I did sometimes bump into bad apples who would insult others, myself included, at the drop of a hat, I usually get by fine.
