My biggest complaint is that following completion of the main story lines, the only thing left to do is build your characters, however the resin system which is used to gain the materials for this has not been updated for quite some time. In the past months there have been several major updates which have basically doubled the number world bosses, however nothing else has changed. It gets very boring waiting for resin to replenish and I haven't played often lately bc there's very little to do.
