cavalry archers, and other lost units

[Pocus]

What has been done to get us have a bit more interest in cavalry archer (a shortbowman on horse costing 30 gold in doms I). It was debated a time that perhaps they would have a bonus in province movement, but I think this was abandoned. So do they simply cost less now?

And what about some forgotten units that few if any players (the experienced ones at least ) used, like the velites, cardaces, etc. ? Are they now tweaked (cost a bit less, or a slight increase in stats).
