All 3 would need to be space combat related.
1. Space combat should involve a pvp war zone, this would help bring more subs.
2. Space combat doesn't need to have much of a story line, just make it free space and multi player.
3 . Plain and simple, make space more of an mmo because in its current state it has nothing to do with the Star Wars feel. Make it explorable, have the ability to use shields, multiple weapons and even scanning abilities.
This game needs an mmo space element bad. It will increase subs for sure.
Just my opinion.
