How would be the best way to go about doing these? I've tried shouting in Jeuno once before (yeah, I know, "once", but certainly willing to try again though), but would San d'Oria zones (where these quests take place) work? Or... am I going to have to hope there's still a nation-separated linkshell out there that will take me? I... think my current one's dead. Or maybe it's sleeping. I'm still trying to decide.
Anyway, I'd be content to ignore these if it weren't for Mage's Ballad.
Actually, I'd like to ask in general how difficult it would be now to get people together for older quests/events?
