I don't understand your point of being selfish because I know that forum memebers can't merit themselves but talking about being careless in holding obtained Sensible merits without giving them out before it decays, then it's absolutely a nonsense act.
Merits can actually speculate if holders grants them usefully but without the Merit source, I don't think if we can actually generate more to the forum because looking at the forum on basis, I see newbies on board and there's been a lot of quality post in the forum which can even drain the sendable merits of there's no source to regenerate more.
