It's not considered an exploit. They said it was fine to do last week. I wouldn't mind if they keep it like this since they nerfed the credit payout. It's a good way to gear up while lvling and a good way to lvl.
This really needs a solution ASAP. It's a limited time event and time is just being wasted now. The cannon being added to the life day vendor instead of the snowball seems the simplest solution.
i'm confused, where is the lvl60 char token? or what did you mean by "Receive a code you can give a friend which will give them access to Chapter I: The Hunt along with a free level 60"
