For example the handbook says complete weekly missions at most 5 times per week, S-ranked at most 2 times per week. It makes it seem like the completion of one group is separate from the other, instead of combined. Is an extra 300k xp/week really going to destroy the level curve Oasis?
Yeah I should have completed them first, I did last week and didn't notice losing the extra weekly missions I guess, but it was definitely obvious this week.
