@ OP
The responses are given in magnitude of how overpowered they are.
Vasari- Giving vasari control of your most important ship's movements to any degree would be giving them FAR too much power in the game, well beyond any imbalance we've seen yet.
Advent- Very overpowered in the same way as the vasari idea. Its more balanced than the vasari proposal however, because of the sheer economic/time/empire requirements to make this possible in a competitive sense. So by sheer magnitude of OP, the vasari idea wins.
TEC- Didn't I post this idea first? Thanks for the compliment. 
This idea is relatively balanced with existing game mechanics, as long as the other superweapons get improved as well.
@ 2v1 conversation
You can improve any players 2v1, and 3v1 situation by allowing all starbases to have movement, much like my other thread on the matter.
That way the TEC and Advent investments in starbases become a valid form of defense. This is the main reason why the vasari starbases are so good at defense, and can deal with 2v1 situations quite well against early game fleets.
@Just Jim
I'm a big follower of Sun Tsu's "The Art of War", so I'm always looking for every advantage I can find, such as fighting very defensively if I'm playing the TL. It's how the TL were designed. If I'm playing TR I would play much more offensively.
So am I, any nuggets of wisdom? The high concept I got from reading that book is that you need to put your men in the position to make them believe they are fighting for their lives. The good general has his hands on the reigns of his men's beliefs, and what they know about the situation. Morale played a greater role in hand to hand/weapon to weapon combat then it does in modern warfare. This is why the military nowadays has the policy that 'your morale is your responsibility', because ensuring good troop morale isn't as important anymore(and it costs a lot) with all of these technological constructs we use to fight with.
It can be done... but like Sun Tsu advises... make the enemy fight at a place of YOUR choosing, not his...
This is the basic defense/offense setup of the game. The point of many of these balance issues is not the fact that this is true in sins, its the fact that the defensive capabilities of the races are far from being balanced.
Its more of a development problem, where "traditional" game design says that for good real time strategy you need to have low defense, high offense action. Sins is a game that is designed so that having a strong defense can still be overcome with titans, so the conventional wisdom is thrown upside down and therefore irrelevant. The Advent and TEC are still forced into the conventional box however.
The vasari are the only race that break the conventional wisdom of this traditional RTS game design, and look, they are the strongest race of the 3 factions. This is not a mysterious coincidence.
