F2P needs everything, but we don't get it do we? Suggesting things for F2P will NOT happen unless Jagex HAS to have it. Such as the whole sleeping back fatigue thing back in Runescape Classic, it wasn't a choice.
That has pros and cons. Pros: It may stop the flow of begging. (Duh) Cons: People will donate things like burnt bread and eventually the 'tree' will be cluttered up. I however am on the fence with this idea, but I think if they do do it there should be like a block that allows useless items to be contributed.
