I find the exact same problem on Lindblum to be honest with you.Even people shouting are becoming picky with the classes I find.This is what is making these quests so long, gathering a party is really tough. Luckily I've gotten the classes I want done and I like to think my reputation is high I don't think I have ever made anyone mad or ever not helped someone who needed it even randoms but still I agree it is frustrating.
