Epeiros looks like they have a number of provinces that can really churn out the money though - with ports and markets in every province, and mines in some too. It looks like Thermon is going to give you grief! It always seems to be one of the toughest places in EB (to me) to take. I like seeing Epeiros occasionally take greece though - it doesn't happen that much, but it does sometimes. If Epeiros has Makedonia as a protectorate, they may be getting cash from Pella too (which has tons).

I like the distribution over almost all of that map actually - except maybe the Baktrians in the steppe and the Ptolemies insisting on going west.
