My initial thoughts can be found here
I'm very much leaning towards getting rid of the irregular size and having everything that fell into
Small-Medium Size(Halflings-Humans) 20mm or 25mm
Medium-Large Size( Orcs,bugbears) 25mm or 30mm
be based on a 25mm base. I don't think it would make much difference and I'd be able to import the troops to say Fantasy Warriors or Armies of Arcana.
Anyone playing Battlesystem have thoughts?
