Right now there are only 6 player ships per server correct?
Why not up the amount to 8, maybe 10, or possibly even 12?
At the moment the servers feel a bit dead, and the world a bit lifeless without some kind of activity going on.
Sure I understand that a ton of ships on a server would affect PvE players, but I feel the alliance system would get more use and actually make cohesive alliances if there was a player threat to defend against Lets face it, some people play so they can go steal treasure from other players.
Once someone allies with just 2 other ships then as a whole they have control of half the playable server, but if there were more ships then there'd maybe be more fleet battles. Not to mention that having a full server ally up with each other would be more difficult and would mitigate the instances of full PvE servers.
