Yeah, I made it through that fight without any real problems. The final fight with Gafgarion will result in Zack crystallizing, so don't use him there yet. Oh and I think I figured out the problem with Queklain: the spell doesn't have a name (I think) or a spell quote. I have an image that shows this, but it doesn't want to upload anywhere...
And those two Lv. 99 Rangers at Riovanes are gonna be tough...they have some phenomenal stats, phenomenal equipment, and perfect range. So I'm holding off on that fight till a fix is implemented. Otherwise, everything has been pretty smooth, aside from what's been mentioned.
