Ifrit needs to be made harder. Solo tank and stunbotted ifrit today all at once. second tank D/C or something but we just ended up letting Ifrit cast eruption through first phase then since second and third phase are on easily recognized patterns I was able to just interrupt him while maintaining threat the entire time.... Granted i have done this bastard pushing 40 times now, sword still has not dropped, and have his patterns perfectly memorized but still he should not be so predictable.
at this point i am done with Ifrit and will just have to progress without the sword. Future PLDs, save time and just get the WP drop.
