I'm not the most eloquent either, but maybe I can explain what I understood from your words.

You say that it could be a conflict of interest, because the manager could use his ability to give merits to a certain user to increase his ranking and thus be able to participate in the campaign or have a higher level of payment. Doing so can provide one user with advantages over another.

For example: imagine that I was still a Hero, and a manager wanted me to participate in a campaign that only accepts Legendary. I need 50 merits to level up. The manager being a source of merit, would give me these merits to raise my level, and so I could participate in the campaign.

Was this your idea @philipma1957?
