We did our game. Lots of fun, buckets of dice...orcs. Here is a suggestion. Bikers could charge and press the trigger as they do. This ability for speed armies has to cost though. 40 points seem like a good trade.
It was lots of fun, and got to use toys that have not hit the table in years.
yes, the battle brothers lost, but the army composition was not good for a counter to a speed army.
