My English is very bad.
This update is practically done only in order to farm 5* dungeon, but their distance from each other is too far, that is, they are rare. This increases too much the time it takes to get to the next one.
Why do we have to stop and spend time on the usual 1* dungeon? He completely lost his meaning in his existence. Dungeon 1* increases the time we need to spend on the game, achieving the goal.
I think that the distance of 5* dungeons should be reduced and the number of 5* dungeons should be increased.
