While I appreciate ET's attempts at running missions, he really doesn't. I have been in the area of a few of his missions and all they are is another horde pointed in a single direction. JG11 is a great squad and I have had the pleasure to wing with them a number of times. They are VERY squad orientated and try very hard to really immerse them selves into the game play. Watching dar and planning intercepts are all part and parcel of that.
While ET does get people together, he rarely runs a mission. Of the time I've along he points out a few turns and then has everyone flatten a base and try to cap it so the troops get in. Missions are when you have high alt buffs with even higher alt fighter cover timed to arrive at a target after either a fighter sweep has drawn off the defensive cover, or just as the defensive cover is dragged to the deck.
Buffs should have assigned targets, clean up guys should be assigned just in case a target is missed. Goons/M3's should have cover so your not always losing them just when you need them most. Goons should lift and take the long way to targets and not fly in predictable strait lines from one base to another.
The problem is when flying high cover you can't run off and chase guys through the ack, you have a job to do and may never fire a shot. Flying the long way around is boring. This kind of flying just isn't for many players.
Having two sides wouldn't get rid of the spies any more than changing the side switch time to 12 hours does. Nor would it help even up the sides and make better game play. The only thing that will make better game play is the player start playing better. Either voluntarily, or but new rules instated by HTC.
