Man, I'm glad it's not just me as well. I'm brushing up on my Anton familiarity in anticipation of the upcoming campaign. So I jump into some instant action scenarios against AI, and holy crap.
They get my wingman in about 10 or 15 seconds, then are unshakable on my tail shortly thereafter. The only ones I seem to have a chance against are the Thunderbolts, and that is really only if I happen to get a few hits in one of them at the beginning when in the head to head merge.
