I think we need to add more opportunities to accumulate Orbs. Because when you have completed all the plot, additional, and special missions, then there is simply nowhere to take the hordes, and the chances of interesting characters falling out, in banners, seem to be too small, for so difficult and long accumulated orbs, either nothing falls out, or copies fall out, which is very frustrating.

The amount of orbs we "can" get is limited but it's okay. It depends how good you can manage your spending. You don't have to summon on every banner and even if then you save either for your favourite units or big banners like eom or eoy.
