Bots no longer stand there helplessly when the match starts. They will now properly target you without you attacking them. You can no longer duel yourself. Multiple matches can no longer happen in the same arena. You should no longer lose elo when winning. Spectators are now put into adventure mode (no more placing blocks mid-match!) Spectators can no longer pick-up items. Elo formulas have been adjusted. You should no longer lose elo when winning thanks to modified formula. (Still needs testing) Amount of won and lost elo has been altered (the cap is still +-300 elo, which is doable but difficult to obtain).
