Well - AI units use mostly all of their skills - and that is better than many other games (other games had problems using "wait" or abilities/ spells...)

Developers are well aware of the AI level of their game - that is why your enemies have much more units than you do.... would be AI brilliant as you would like it to be - you would never win battles like "fighting your own double army" etc.

So actualy it is what I like so much on this type of single player games - players skills improve but AI skills do not - so longer you play, better tactics you can prepare - so you can demolish and clear nearly any battlefield you like and enjoy it as well...
