Aggressive actions? Yes, but as it stands now, in the current system, these "aggressive" actions have no bearing at all on the success or failure of an invasion, because it always comes down to the lightsaber battle on the ground, or the ship battle in the air, or the duel by the console that has some mystical button that will end the war. The planets "defenses" of let's say, a shield generator, Anti-Aircraft turrets, etc, are null and void, because they get dismissed as either A) being neutralized in a post or two, or
Despite the amount of Anti-Aircraft defenses, the 501st and 502nd were able to touch down, and deploy their troops with acceptable losses... or C) Get ignored all together.
Which comes back to the point of NPC defenses (and attackers forces for that matter), getting steam rolled, having little to no bearing on the outcome, and for non-combatants (when I say that, I mean people that are not going to fight hand to hand on the ground or in the air on a ship), the current system holds little to no appeal at all for some of us.
