The fight was definitely designed with Japanese network infrastructure in mind. It's way too unforgiving for people in the West who are unlucky enough to have shitty ISPs. I think some tweaks need to be made to make it more reasonable in general. Our FC has gotten a number of people through it, but there are some that occasionally lag, and it's just not going to be possible for them. Combined with the fact that Ifrit EX is orders of magnitude easier, I'm wondering exactly what YoshiP was thinking when he designed some of this.
