Shield-wall is supposedly fixed for the new DLC, but we currently don't have a properly working. We are testing it out though.
Also for expedience we will first just be using current rosters.
So just Cammilan units for Rome. Non reform Greek rosters, and non reformed Barbarian rosters.
That's just to get everything functional and save time up front so people can play the campaign.
Afterwards, especially when we go back and do a run-through of the sub campaigns tutu and everything up we will likely have a far more historical roster for it.
Those are the current plans anyway.
