The concept for voidstar exists in other ames with varying success, from WOW's incarnation to Aions very successful Dredgion, SWTOR produces the sloppy voidstar, with the least amount of imagination possible. The concept is rock solid, the implementation in swtor isn't very.....fun, especially given the map layouts.
But don't get me started on map layouts. Alderaan 's' shape? WOW. funnel us more BW, we are sheep.
