Oh man.. I always give people a few chances first incase they are new, but if they can't learn a boss that has no randomness to it after the 3rd try I just leave.
Hard mode Garuda, one guy doesn't say anything until he finishes examining all existing party members, then proceeds to tell which ones to leave and never come back until they gear up. Wow.
Another Garuda- I'm a pld and we had this war insist on being MT. Ok by me, must mean he knows what to do. Wrong. So we wipe and I explain to him what to do. He doesn't say anything and we try again, same mistakes, we wipe again. He isn't moving her during the tornado phase. So several of us explain it yet again. 3rd try. We wipe yet again for the same reasons. Then I kid you not, he proceeds to ask us what to do.....
"Hard" mode Ifrit. I've done it 20+ times, tanking and stunning, with no luck on my weapon drop. I ask the other pld if he can stun and he goes off about me not being able to tank because he is "wearing" the Ifrit weapon and I'm not..
Also while on stun duty on Ifrit others were not listening when I told nobody else to stun, so of course mine get resisted. I insist that it was resisted as clearly stated in my battle log. One of the healers refuses to believe that they can be resisted and goes off on how I had missed half of the ones before that one too, which was entirely false. He promptly drops.
Sorry, ranting lol
