1- Remove unnecessary running & loading screens between planets.
You have mentioned allowing speeders in space stations- I'll go you one better.
The short catwalk between your ship entrance and a planet's space station is entirely pointless. Remove it.
If there are any quests where you talk to an NPC on the catwalk, move them to just outside the elevator (which would now be a direct entrance to your ship).
2- Make PVP medkits purchasable with Centurion commendations
Seriously, it will keep them useful for something other than companion gear
3- Ilum
Having munitions spawn at Central, North AND South would make the world pvp less painful.
Big zergs would naturally split up into 3 allowing the smaller side a chance to get in and get some kills before being swamped in a sea of red due to increased travel time between nodes instead of across a node.
The bloodthirsty can go looking for a fight & the more casual can grab their boxes at a quiet node and go.
And to be clear, I'm Imperial on TJJT so I'm the one normally outnumbering- it's no fun for either side.... even less fun for the underdog I presume
