Monks would start on "no attack". If you put agressive, wil try to convert every military unit (maybe even vilies) that passes by.
Hate to micro them.
That makes Aztecs insanely overpowered. Make 75 monks. Stand there. You win!
1. I played AoM a lot, and noticed, that there are some improvements for the gameplay, which might be introduced to aoc, too. They are:
1.1 If you select multiple buildings in aom and produce a unit, the unit is produced in every building, if you try the same in aoc, only one building is producing the unit.
1.2 In AoM, there is a button, with which you can tell a building, to keep building one unit, it is some sort of an infinite queue. You identify the buildings, you told to do so by a green circle above them in aom.
If one or both of them could be added it would be a great improvement I think.
3. If you have to delete several units, like villagers, if you want to have more capacity for your army, or buildings, if you want to tear down your own wall or something like that, you have to press delete again and again and again. Maybe you could add a button with the combination shift+del to delete all selected units.
7. I know, it will be hard, but it would be great, if you are able to integrate a real spectator mode, so that a spectator can see the whole map and loses his ability to interact with the game.
