I talked to a rep about it and was told to just report it here, though I wouldn't quite think of it as a bug per-se. I've also talked with several other people on Balmung about it previously, and they agree that Ifrit's behavior and some of his attacks' patterns have changed.

I just would like confirmation about whether there have been tweaks made to the Ifrit battle.

If not, then reporting it as a bug with my latest Ifrit fights having been today in the last couple of hours (May 23rd, 2012 - between 2:30pm and 4:30pm I'd estimate).
