I believe one important change needs to be added to ARENA: When you search for a new opponent, you will NOT meet the same player two times in a row in 1 VS 1 games (not 3 or more players). This will also reduce (but not eliminate) the chance of cheating.
Other change, or is it already implemented: A limit to how many turn-based arena matches a player can have at once in a spesific game. 15 maybe?
