Yes definatly Raging Amish, the scout ability is nuts.
At this point in the game, your TEC tech tree should have granted you lots of producton speed bonuses. Make sure that you have at least 1 frigate factory for every 4 or 5 planets, more or less depending on the game size.
Use the hotkey in game to select all factories (not sure of the default anymore, mine is bound to my mouse), and pump out streams of scouts.
You'll need at least 15-20 per planet to make a giant dent into well protected space, and each scout ability is on a cooldown timer after its set, first 10 seconds (for the detonation), and then the final cooldown for reuse is about 1 minute. Also, they get the "Infallable Jump-Drive" ability, so you can do this all the way to the back of the Vasari planet range, and they probabbly cant stop all of them.
Unless the planet is heavily defended from attacks with lots of troops (defenses will not be able to stop that large swarm), you can shut down his buildings pretty quickly.
Also note that it is important when playing as TEC to have a very strong economy. Maximize your trade income, keep an eye on the trade route itself, max out your planetary improvements for population (no negative penalties!), and ensure that you are using the market to its fullest effectivness. (see some other posts in the strategy section for more info on that).
Because of patch 1.04, Vasari are no longer able to spawn RA past their fleet maximum, you should have no trouble with having a stronger economy that DOESNT just go away once a single type of structure is down. They also lack the ability with their super-weapon to outright destroy your planets, but they will be able to damage buildings and units with enough super-weapons. Shut them down with the Novalith.
As another note, RA is on a somewhat long cooldown, its about 3 minutes. The enemy will have to have quite a large planet base to call in so many reinforcements so quickly. Since they will have a lot of their tactical slots filled with phase gates, you need to boost your Novalith production, and hold your postion until you can completely wipe them out with heavy bombardment.
Since the Vasari are terrorisim-tactics figthers, the best way to deal with them is to find out where they are at all times, destroy their economy, and assault the enemy with long-lasting forces. The TEC are good at all 3, with our remote sensor ability from scouts, Novalith Cannon, and Command/Repair cruisers. I really reccomend the latter in large numbers, in conjunction with some flak frigates to keep the enemy strikecraft off of you. Also, the TEC Battleship ability "Flak Burst" set to autocast.
Light Frigates are also key late game, to disable enemy anti-matter reserves, and since its Vasari, no anti-matter = no game. However, they regenerate quickly with their technologies.
Remember, Vasari fight with terrorisim tactics, TEC fight with long lasting troops. I see a lot of combat oriented troops in your makeup, try to throw in a lot more support craft into your mix to protect your investments, or to just make them outright unkillable.
- Sure they have lots of troops, but if they kill 1 every 15-20 seconds insted of 8 or 10, it doesnt really matter how many they have! Make sure you emphasize that.
Edit1: Another important fact that I just remembered, is the tech "Insurgency". The higher your culture with the opposing forces planet, the more insurgents they recieve. With your economy, the only way to stop an planet filled with culture is to build lots of anti-culture towers themselves, which leaves those forward planets ripe for a Novalith blast and scouts. Continue to leap frog until the enemy loses enough position for you to move in and colonize. Dig in, and do it again ad nauseam.
