There are two kind of people on this forum, one who can't get merits and cry about this merit system and second are those who are doing fine job even after merit system implementation these people are fine with merit system.
I don't think there is going to be anymore changes in merit system. Adapt or leave.
Definitely we need some tweaks because not all the good posts are going to get merits so if someone posting meritable posts but on the wrong boards (where merit sources are not available) then how he is going to rank up?
He should have to change his posting habits for to rankup?
