Cortez theory is as follows:

Artillery, hashishin, naphta throwers, and the like are special troops. They take two (or more) years to produce. In the Cortez Play Book, they are not in the same category as archers, footmen or cavalry.

There should be some number, perhaps two or four slots, for these special troop types.

The current arrangement favors greatly the player over the AI, who will take four useless artillery on an attack, when. Cortez does take advantage of this, but does not like it. He feels it is cheating, and tries to destroy the artillery asap so he can face the entire army.

When Cortez plays a Muslim faction, he keeps one naptha and one hashinin with each general, it would be great to have special slots for these, but not required. Artillery should have special slots.

As far as the debate between 20 unit and 40 or 60 man units, the infinite wisdom our creators gave you a solution... if one doesn't feel the unit is balanced, one may change the unit size Mod away
