Need to really ask some people - Why are you trying to get every unit so desperately? I can understand if you actually use that unit, but something like Garret is probably the worst thing ever. If you spend a whole day trying to get that, would it not have been better to just farm phalanx 2 for aff items and fairies plus whatever story mode map you farm for exp?

Personally i got Julian since i use him, and want to CR/SU my main, and skip trying to get Garret, Kerry and Stray since i will never actually use them. I'll run those maps once for the SC and then never look back at them. Bernice and Betty i'll probably try to get since i want to CR/SU my mains.
