what really sucks are most of them are in the early stages of the event, such as garrett on 2nd day, iris on 3rd or 4th (lazy to check), while all the probably more needed units are at the back, =/
so for example today if we dont intend to farm garrett, there's only julian to farm, meh. so if we already managed to get julian, might as well just get garrett with the spare stamina or something
