Well i would like to see more Neutral planets and NPC.. like if u have a base you could move out with a small force or a singel unit to explore the galaxy and maybe find some useful things like reqruiting units or something like that.
and it would be cool if it had some EU content like if you explore an planet in the outer rim you could find some temple or something and find some intresting things like reading books or holos (just an ad to the story or something like from KOTOR games)
this would be cool couse then you could travel just for fun and building a base so you dont just fight in the war all the time.
some RPG elements?? lvl up and so? i liked that in warcraft3 you could lvl up ur heroes.
