Honestly, I can't understand why you thought this defence was too strong for any undersize attacks. I'd be disappointed if I only reached the score he did. Lots of solo options on offer.
Taking a bad team to r8 just makes it a crazy expensive bad team. I wish the Rouge One team was better too. But it's not.
Edit- I'd just like to add, good on you OP for letting the forums act as a filter for suspected cheating. Best to not bog down the obviously limited resources of the CG cheat team with this kind of thing. I suspect that most of their time is wasted investigating legit wins.
