Hello,
I attacked and spied lot of people (my score is around 400k), i didn't see all possible kind of armies and tactics but there is one thing that weird and all people I met have almost none of them: support units.
I pretty like this concept, even it's not really developped but still cool. The problem is the ratio for them and the calculate algorithm. You need 10 support unit for 1 normal unit ! And that take also poloms and pochteca !
Even in background, that make no sense but more in the ingame world. If you have a little army of 100 hunters and 200 poloms, you need 3000 quips and 3000 shamans to reach the max bonus 
For me the solution is pretty easy (but maybe hard to balance), a support unit can support multiple normal unit AND boost only warriors : lancers, bows, hunters, nahuals, eagles, jaguars, atlants and ek chua. And that's it !
Of course for balance the game, the price must be changed and be corolate to how many unit can be boosted. Stats must be changed as well and maybe amazon warriors too for matching with this changing. With that, we can finally use support units in all battles and that can make sense !
Thanks for reading
