What I've been noticing in Boom Beach is how it matches you up to random opponents - being a former CoC player, I think having a pick on which opponent you fight is a more fair way of playing with others. Every time I get a new opponent in BB, the base is either undestroyable and loaded with defences or a lower level base with only one mortar and sniper tower. (My HQ is level 5) I would suggest something like a list of opponents around the same difficulty as yourself and the cost to fight the opponent would vary on his experience level/amount of medals. This way the BB multiplayer system would be much fairer
