Will gach, cubes etc. soon become illegal?

theres way more nub bosses than high level bosses

Obviously high level bosses would have a higher cube drop rate than low level ones.
And if low leveled ones dropped it, every boss map would be camped 24/7, and all bosses would turn into ks and dc wars(Remember Bigfoot?)
And it would be stupid to have Mano dropping something as valuable as cubes anyway..
I'd assume only manon/Griffey/Pianus/pap and higher would drop cubes.
