Can you please address the boosters in arena. You have players working together in a game mode that isn't designed to be team work, to boost each others ranking. While there is nothing stated explicitly forbidding this action, it is intentionally being used to gain an advantage above others, but in doing so they are skirting the design of arena. This is manipulating a design flaw to gain advantage. Please look into discouraging this under handed playing, and please punish players who think this is okay.
