I think I'm going to pay particular attention to the balance of the temple guard. When I made them I was comparing Itza with Mictlan, due to their many similarities, and envisioned the Temple Guard as being on par with Jaguar Warriors in their overall awesomeness. The problem there is that Mictlanese troops are mostly rubbish, while Itza has an excellent range of troops and avoids many of the disadvantages of Mictlan to boot.

The sacred summons are also somewhat eclipsed by the Temple Guard, who benefit from a rather different bless (E9 actually works on them for instance and their durability favours regen and reinvig). So perhaps they just need a cost hike.

I doubt I will increase resource costs across the board. Itza are pretty much a sloth nation, since their armour and weaponry is largely either biological or naturally occuring.
