The merit system has a lot of flaws, you are at the mercy of higher ranked members who are as diverse as can be, some may not be ready or willing to give merits at all and some may probably not know a quality post if they see one, if we do the maths for higher ranked members in a position to give out merits we will now be left with a small percentage of objective and progressive members in that category who may not even read your posts.
Not correct, there are merit sources who will not be partial. I have also seen a lot of high rank members giving merits to new members.
