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

And boy, they are much worse! My wife got all 20 Dews spending less time than she has for 2 Soul lights so far at Poison Poopas.

Same here.
The Soul Lights for the first level took about 1.5-2 hours each, on 4x drop. The next two levels went much better, around 1 per half hour. All in all, took me an estimated 30 hours of 4x drop to get level 3 SD. Seems like Nexon really don't want these skills to become commonplace.
