I've fought Ifrit probably 30-40 times and have beat him 20-25 times and I haven't even seen Ifrit's claws once.
As a MNK the fight is pretty easy. I usually take out the nails if there's no BLM and have stunned in a pinch in some fights.
I almost want to give up and just get my GC weapon. But now its like I've gotten this far, I might as well keep trying.
Actually if I'm not in a rush, or don't think about my weapon not dropping the whole process isn't too bad. After work I log on, queue up, mine, get a couple of successful runs in and its not too bad...But after the fight if I see one of those books instead of the claws I want to strangle something.
