1. Open World PvP - Capture/defend open world PvP objectives. Would be cool to have it combined with some interactive daily event such as the Galactic Civil War from Star Wars Galaxies when one had to defend 3 cities, one each hour, build npc troops, turrets for the defences and vehicles for the attack.
2. Player housing and player/guild cities on certain planets with possibility to decorate and add furniture to your house and, at least until that is created - fully modifiable ships.
3. A group travel function where you can travel to where the leader is located and speeders able to carry more than the player.
Cheers
EDIT: Oh and thanks for the recent Gree event that made Ilum feel alive again, reputation and last cartel pack. Last but not least the responses from Bioware on the forum - Great job Bioware - keep it up
