Once people realized how to game the system and how rarely people get punished for PvP incidents outside of obvious harassment, the misconduct taking place in Feast has increased 10 fold. I mean why not cheat when there are no consequences?
If a competitive game mode like this is going to continue with rare rewards, it needs much stricter and more active moderation. If SE can't do that then stop giving out any sort of ranked reward that would incentivize bad behavior. Just give us Magna Roader recolors from here on out.
