So….you don’t want newbie to gain high kill rate as you do huh? Why don’t just make a diff that base on character specialize that gain through experience? Something like RIP tyre that circulate around behind wall to confuse enemy before surprise kill several of them instead of run right in front of enemy to get destroy. Something like hide behind wall then throw trap right at enemy then bomb again for instant kill instead of just lay trap in open space waiting for enemy to spot it and destroy trap.
