As the title says, we are just updated our 1v1 challenge / wargames system and now ure able to challenge other player's groups for 2v2 and 3v3 arena also (depending of the size of both groups).
To challenge someone for 1v1 wargame, both players should not have any party groups, otherwise the groups will be invited to a wargame for arena type equal to both group's size.
Example: If both groups have 2 players each, when you type the command .challenge your group and your challenged player's group will be invited to a 2v2 wargame. Its exactly the same for 3v3 wargames.
