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

i'm now 7/10 done with 1st set of orbs @.@ jesus only 2 orbs in 2 hours of 4x drops. i feel like my 2x drop is working better than 4x drop considering i found 2 in 1 1/2 hours of 2x drops @.@

I got 3 Dews in 3 hours on 2x drop. Please Cassandra, bring your spring flowers back...

that is rather fast actually. on 4x drop i got 3 dews/hour but on 2x drop it gets so rare. my last 4 dews were found between 5-7 hours of 2x
