The entire idea is to get help to people who are choosing duties nobody wants to fill and providing an increasing reward until the queue fills. Duties that take less than 10 minutes to fill wouldn’t even appear on this list. Easy duties wouldn’t pay a lot because they are easy and would fill quickly so the reward wouldn’t increase. So if anything the incentive is to help with the hard duties because they would sit for longer accruing rewards since less and less people would like to participate in those. It would also discourage toxicity because people would essentially know what they are signing up for, rather than mentors randomly farming the mentor roulette fishing for easy duties.
