From my metagaming artical last codex: (edited somewhat)
Code:
this is a slang term typically said of an army that was easy to use or build, or a creative strategy or other device
you used to win. Typically the losing party will clam your army build was cheezy.
"That all grunt army is so cheezy."
There has not been any archatypes as yet, the front page artical we had here about the all orc army is about the closest you will see to a "cookie" cutter army, there is only so meny combos a person can do, mostly the most effective armys are still the swarm -types, lots of squads with few heros for support.
Thats just the nature of the game so far.
