Well I want to start this idea by saying in order for it to work right the cp drop has to be the same on all monsters. So lets say all monsters are set to 100 cps per kill.
*Vip 1 Zone= Lab Monsters with 50k hp. They drop 150 cps
*Vip 2 Zone= Lab Monsters with 120k hp. They drop 200cps
*Vip 3 Zone= Lab Monsters with 180k hp. They drop 250 cps
*Vip 4 Zone= Lab monsters with 200k hp. They drop 300cps.
Vip 1 would cost 10k cps to get into
Vip 2 would cost 20k cps to get into
Vip 3 would cost 50k cps to get into
Vip 4 would cost 150k cps to get into
It mixes up the ability to hunt, gives the players different monsters and more ways to hunt. People can come up with the best stratagey they can and so forth, Not much editing required. Just a few changes to the lab zone/removing the normal lab. But i think its an idea that has potential.
