So I think this merit mechanism is unfair, because it would allow those legendary or heroic users to profit from the merit mechanisms, and not to upgrade those who can not afford it.
Yeah I think its not good, maybe those who are selling their merit should banned automatically or maybe have some warning. Buying merit is not good, merit should need to work hard before you can get it. Moderators should do something about this.
Work Hard? The system is not fair. I can guarantee that we will see situations where a mediocre post could get many merits than long useful posts. It only favor higher ranks because they will get less competitors on bounties.
