I particularly like your location bonus for Arena, with the rotation each month. It would be very nice and would probably shake up the rankings a bit. And not all shards need to have the same location at the same time.
Instead of ship raids, I'd like to see a string of PvE ship battles, like the LS/DS/Cantina battles. With a few more ships (like TIE Interceptor, A-Wing, Ebon Hawk, etc - and their pilots). Raids are too dependent on your guild, and it may be frustrating if you have to wait for all your guildmates to be ready to start them.
Agree too on mod management. At least, being able to group mods as a given set, or simplifying the way you can take a mod off of a character to give to another.
