Uncollected difficulty...really?
One can easily become uncollected with 4*s...3*s even but can hardly do the uncollected difficulty in event quest... where's the Sense in that? The previous and recent UC event has proved that the "uncollected difficulty" is way too overpowered than what someone who's recently uncollected can handle.
I think that difficulty should be nerfed and a new difficulty created for the high end players, to reduce the frustration of those that are recently uncollected.
