Is anyone else having a hard time with the dews on regular Adventurers?

It doesn't seem that bad after the first set, it took me about 20 hours of 1x/2x/4x drop while i'm already at 7/10 for the second set after 5 hours of 2x drop. Going to see how bad the third set is soon.

Yeah, first part took me around 12 hours to finish.
I'm at 5/10 of the 2nd set already with only hunting for 1 hour.

This is on constant 4x (Card + Lucky Winter) btw.
