Yup, exactly the plan.

The Hai are actually of little consequence. In my now defunct 0.81a campaign as Pontos, I held them at bay at 2 river crossings. They tried to come across east of Amaseia, but my fort there in the mountain pass stopped that effort. Sinope and Crimea kept them quite busy, otherwise.

I am debating whether to make Antioch government 4 or not. I really want the 3span artillery, and I can only get it in Antiocheia, Mytilene or Sinope, and ONLY with lvl 5 regional MICs
