Hackers are the ones who hate the level system most, because it takes a lot of time for them to upgrade. I have a person I know who has two accounts blocked, one at level 15 and the other at level 12. He kills everyone he sees. I can only be happy that he has been blocked.
It will be more difficult to upgrade without buying a membership, which is good. Who will buy a membership on an account that will be blocked anytime and anywhere? Very few.
