How hard would it be to create defences for your bases and ships to defend you base in order to have a fleet event. This event could be something that you build up to after say achieving a tier III level of defenses, and then have a special event contribution on a fleet tab under a new section, fleet defenses?? I think that would be really cool. Maybe if that works have pvp events where opposing fleets can declare war on each other so we can attack each others bases. Imagine how many pvpers would come to this game! Pvp would actually have a somewhat value in this game. What do you think??
