Minor balance change: For the attack action, if an attack occurs from an attacking group (3) onto a smaller pack (1 or 2), only a 1v1 or a 2v2 would occur, even though all 3 attackers submitted the action. To balance this out, if the attackers attack a pack with 2 players (2v2), the third attacker will give a +10 contentment bonus on the attacker's stats. Similarly, if they attack a pack with 1 player (1v1), the second and third wolf will give a +20 (total) contentment bonus. This is a necessary change. Note that it will still always require the 3 pack leaders + elders to attack, regardless of the pack size that is being attacked.
Even though there are a lot of words, this will only affect the game balance minimally.
