Casual Match Improvements
At the end of a Casual match, players will now be automatically formed into a new match with the same players and teams. You'll also get to vote on which map the new match will take place on.
New Autobalancing System
We're introducing a new autobalance system for Casual Matches AND COMMUNITY SERVERS that asks for volunteers to switch sides. Casual matches will reward you for switching teams by giving you the chance to earn bonus XP!
