The doctrine is neither cheese nor is it weak. Bitching on balance team in this case is just unfair.
The definition by Liquidpedia: "Cheese is a pejorative expression which refers to a strategy that is highly unconventional and designed to take one's opponent by surprise. In general, cheese is hard to beat if not scouted but easy to defeat if it is scouted."
Replace scouted (which is a term that mainly applies to pure RTS than RTT) for been prepared and knowing how to deal with it.
The CoH community associates cheese = bad which is not the case. Some people have some expectations from reality in which they should be playing games like Men of War or Steel Division instead.
