I'm sorta new, could someone please explain to me how farming for 5th copies of event CEs works? From what i understand we can get 4 copies in shops/from missions/etc, but we gotta farm for the 5th copy if we want to MLB. Just how rare are these things?? Or is there some requirement that needs to be fulfilled in order for them to start dropping? Or do some quests have a higher chance to drop than others? ...or am i just really, really unlucky? I missed out on a bunch of mlb event ces already, do i just need to step up my farming game?
