I don't offend our opinion but if the merit requirements for the Full member rank is 20 or 25, full members are not too different than Members.
Non-difference in their post quality compared to closest lower rank (the Member rank) and there are more Full member users.

I assume with 100-required merits for Full member rank, there are 1000 self-made Full members.
Then, if the requirement reduces to 25 merits (as you wanted), there are likely 4000 self-made Full members.
Those figures above are only assumed, not real ones but from the assumption and results you can see your odds to be accepted in campaigns (4000 applicants rather than only 1000 applicants) will be decreased roughly four times with 25-required merits for the Full member rank. Do you want it?
