I'm currently busy to change the edu a little bit according to my taste. There are not much changes however. For example I added ap feature to some mounted javelinmen (I have to test the impact to unit balance however).

One problem for me are the slingers. They already lost the ap feature (except the Balearic slingers who got a very low reach on the other hand) and now I'm considering the range of the units. How did you calculate this?

The Celtic slingers have a reach of 200 m for instance, the Sphendonetai of ~180 m. Greek and Roman slingers often used lead glandes to sling further. Did the Celts use them too? I know that great amounts of sling stones are found in Celtic hill forts but have no knowedge of lead shots. If the Celts used mostly stone projectiles I would give them less reach than the Greek slingers.
