It is highly unlikely that we would be able to number the legions.
It is impossible to give them unique standards on the campaign map or battle map.
As we cannot name legions automatically we cannot then assign them traits that would reference these (there would be no way for there to be any consistency for them).

Yes, we will need to make new animations for many units.

The senate will very likely appear as the "Council of Nobles" mechanic from MTW2 and would give missions. As in EBI your generals can be elected to positions in the senate. The senate will not appear as a separate faction. We could not have the senate propose new laws, but it could be possible to have certain missions associated with certain events or actions by the player - however we have no wish to railroad the player through history.
