The benefits and improvements this will add to the forum is endless, but I just can't mention all, but like I said earlier, it's a crazy idea which not many people would agree to, most especially, those that have hard time earning merits because of lack of quality posts.
on the contrary, the detriment is immeasurable because you're encouraging spamming since everyone will be looking for a way to earn merit in a hard way thereby making countless of posts and on the other hand you're also encouraging merits trade unknowingly. As beneficial your wild idea seems, the harm it can cause weigh higher. My thoughts thou.
