I think that the top 2 players (per team) in PvP should be rewarded with more loot "boxes". So the player that's in first place gets 4 chances at loot, the player in 2nd gets 3 chances at loot. This rewards them for being the top players rather than giving everyone equal chances even if you afk the whole game. You are only giving then more of the "boxes" that loot spawns so not a guarantee of more loot just a greater chance for being top players on the team
