There are not many EZ mod players, but there are people who play EZ mod sometimes to practice, including me :^)
so i'll post anyways, you should be able to overcome overlaps decently fast by playing more, the end.
First with good approximations, workarounds and guesses that very often allow you to hit the pattern not necessarily knowing what the fuck just happened
Then you actually learn to notice the very minor differences between approach circles, read the overlapping numbers, quickly take the combo colors into account, etc. to be able to consistently read such patterns.
EZ on 120-140bpm ar8 maps, the ones you would farm with dt,
:^)
should result in a density that is not as high as your average higher level nomod map capable of giving pp. so I recommend doing that if you find yourself getting sub 70% acc on everything you try EZ mod on. maybe
