In Reach, an assist is defined as "doing 40% or more of the damage required to kill a target that dies to other causes before a shield recharge can occur."
Do assists factor into FFA arena? (Or is Arena strictly team-based in the beta?)
game_normalization = players_per_team / score_to_win
Does this mean that, if a player on your team quits, causing uneven odds (ex. 3v4), the players_per_team value would change? Or is it just the intial amount of players on each team?
