Those Galatian Thorakitai are fearsome, both visually and performance wise. In my Diadochoi campaigns, I like to add some regional flavor in my armies aside from the 1st (Royal) and 2nd (Royal Successor) ones. Currently playing as the Antigonids and I have two Galatian units in my Asia Minor army, they regularly get kill numbers on par with those of my rout-chaser cavalry. I have now added 2 each to my royal armies, which are preparing to invade Italy against Imperial Rome. This will be fun.
Also, KAM, you mentioned tinkering with the Thorax spears; will we see an overhaul in this beta, or is this something further away in the future?
