So, I just ran a pretty successful game with the mod, along with a few others.
Everything seems to run amazingly well. The AI uses most of the units provided. Still having trouble seeing the elephant units. Saw a few, but not a lot. Although, I think that has more to do with the resource being unavailable rather than the AI thinking it's useless.
So yeah. Everything is working fine. And, like I said before, the mercs' pricing, etc. was fine considering the stats.
