It would also be great to see some kind of field artillery in the game. Something related to scorpios, maaaybe even a small catapult. Yes, it would be highly impractical in most cases for field battles without gunpowder, but fun and interesting battles is good. Together with engineers, we could have a dynamic battefield
*Edit* Could also be more relevant for a hybrid siege-battle situation.
This would be cool and a good use of the class system. At the very least, Siege maps should have stakes pre-deployed that damage cavalry riding into them, they should be able to be destroyed but it'd be a nice way to help resist the storm of cav.
