We had such a system in world 5 alliance that i belong to. We all took turn sending 1 hour of resource to an member, to help them grow and everybody got a turn. One problem that came of that was one member got kicked out by multihunter, because a sitter send him some resources. We was reinsated but lost all his resorces and dropped one level. We are trying to figure out a way to still do pushes without anyone getting kicked out.
