That people only use Custom Challenges to boost? Like seriously, Custom challenges I feel were only made to be exploited. Who is going to spend 3 minutes creating a challenge to kill 70 people in Matchmaking, to only get paid 52 cR.
Why don't they just shut down the whole thing. It clearly was a failed idea, and now its only used to get 200,000 cR every hour now for boosters.
AND YES, I will admit right here, I boosted like 200,000 cR with it to see how much you really could make.
