I don't see the issue with ifrit.... he isn't a dps race nor a healing race, and will do just fine with AF white. (and how do you get a GC50 without AK first, no one would have GC50 anyway unless they get carried in AK)

Even with the worse white weapons, at most you'll be getting one or two more turns of ifrit rush...it's not a big deal, the party either knows what they're doing or not.

garuda is way tougher, and more gear sensitive so that is indeed a gear check event.

But generally any fresh level50 with a decent head on their shoulders should be fine with ifrit to chew on, and unless they have really incredible luck, that'll keep them busy for a while.

If anything a sub job check is more important. Being gimp in some important skills is very bad at the start of endgame runs.
