the most best way to declare the OP'ness of a unit.

Racketeer rush on my end seemed like a sure fire way to counter most of the big nasties that are rushed with two coms. Brawler in this case would have been fully countered if I had some vandals.

An intriguing game though.

Racketeer on its own though isn't much. Its a simple force multiplier. Use it to turn a local disadvantage into an advantage. When you combine it with the other units shields have, you have an OP force. Shieldbots synergise extremely well together, unlike other factories it seems.

You can combine Racketeer with any unit. Even Glave + Racketeer can kill a brawler after a while.
