UNIT - Creature Balance + Visual Changes

In my humble opinion, crossbowmen (marksmen) were and remain a practically "forgotten" creature, and this started even before the introduction of alternative upgrades; I know many cases where a higher maximum damage was sacrificed in favor of higher initiative and the ability to shoot over obstacles, which archers possess.
Solution: give crossbowmen either a double shot or the ability to shoot over obstacles, but only if the squad has at least a weekly increase in creatures, in order to maintain basic logic.
