This. Also, like the Annihilaser, gas giants can be sniped if you are still "viably in the game". If annihilaser, all else fails nuke the pole to destroy catalysts, or SXX snipe. If Gas Giant, drop 10 avengers on each jig, even if 10 jigs you can destroy them even as your opponent builds them. If they build 6 or 7 then you just drop avengers on the last built one, destroying it, and the fabbers afterwards, and you drop 4 on 4 seperate ones and destroy as many as you can nearby to spread thin his orbital forces. You will just keep burning down his eco farm every time he establishes it.
