First - I have no idea about IPMS. Surely you just use one of the menus, right?
Second, I'm not too eager to switch servers after I've invested a decent amount into developing this account. However, I might could be persuaded…
One cool thing I read about other servers: The new universes allow “ACS” - I'm not sure exactly what it stands for, but it lets several fleets team up to make an attack (and possibly a defense). it sounds like you can do something like this: Have one fleet leave from a distant location to hit a target and then have a second fleet timed to join the first one before it reaches it's goal. I think it is even possible for different players to join their fleets into one attack (so we could really “team up” on someone)
