You obviously didn't have an arms race in your shard. Your strategy probably doesn't work well against all R9 pilots. Easy time out with strong pilots. I have run up against not being able to take out a single ship, even after ultimate because bomber just won't go down. If opponent manages to both bring in Mk6 and blow hangars, you will never win because you are likely going into ult with only three ships and your next ship being nuked from the hangars. Their dagger is still alive, so you can't TM train it either, so they are getting five ship turns to your three and by the time you get in a reinforcement, you are probably down another ship and have less than a minute left.
