people who only rent can still play in modern, I've heard the rewards are higher there too :P. the biggest problem is cp rent is way too cheap, for 1 dec you already get 10 000 cp. so that wouldn't help, or you would have to set the cp requirement much much higher. but then everyone would be affected and that's bad. Because we can't have another antibot farm measure that harms everyone. and on top of that it wouldn't be as effective against botfarms/extractors anymore in the end
