Arbitrary limitations on in-game functions like champs or sniping show that balance problems are present, capping the number of these things isnt really a solution but a coping mechanism.
So far there hasn't been enough gameplay of the new mod to establish what, if anything is OP. Many people claim certain things are op when they lose to it, but there needs to be widespread agreement to make a conclusion.
