Only played two rounds in the updated arena, but so far, so good.
The new scoring system is much better imho. One player had five extra cards, I pulled ahead of them, then watched them try and catch up with their final throws. Second player, we both had seven cards each, with my final throw I just edged ahead by 20,000. Easily more enjoyable than the old scoring.
Hopefully the cheats have been eliminated as well!
