That was my initial plan as well. never to go past orcs. but its all going so smoothly atm, im now leaning at the, why not go further?
Also it looks kinda great to have a maxed out flying academy in that ultra small city. Only to get loads of free priests that are pretty awesome in tournament

This city is made to make tournament and spire as cheap as possible. every expansion i placed is a diamond one, because they are a bit easier on difficulty as normal ones. (all diamonds are from crafting and spire).
It feels a bit like playing a game you already know completely, over again, only on hard mode this time
