I know that the purpose of this system is to create a better forum with better members but just imagine yourself a full member needing almost 2 years to get to senior. Is that fair?
If two years is what it takes someone to receive 125 merits, then yes, that's fair for that particular person. Particularly since merit and rank do not affect users' ability to participate on the forum. Ranking up is basically eye candy.
Why are so many users complaining like it would be some kind of basic human right to become legendary by posting stuff that no one but their own mother considers useful?
