some objectives are easy to encounter, while others seem impossible and can go whole mq without encountering... should the rates be changed and increased to make objectives more achievable?

example... so far with current climb I have been hunting Ambush! since lvl 32 (now in 60's). Have completed 4x lvl20 maps, 3x lvl15 maps, 3+ lvl10 maps, explored a couple lvl 45+ catas (didn't finish cata though since kept falling through td), all with easy mode deactivated since solo, and still no monsters leaping have encountered groups of 3eps lots of times but not Ambush eps....on the other hand, encountered sneaky, pest, bits, and pinch fairly fast with 1-2maps/cata per.

each climb varies but in general some objectives seem to have way higher chance of encountering than others.
