Yes, I agree. The thing I like about this exercise is it removes any concern for moves after about T65 or so. This allows the player to focus on what really matters for the opening, developing a strong infrastructure.
My intent with working these exercises (and others, I'm sure), is that on Noble I can remove the AI's tendency to interfere with my learning the game and I can master the game mechanics.
Then I can work on warfare at higher levels (axes, cats, etc.) and then make the move upward from Noble.
Now that I've written that, I might have misunderstood your question. I interpreted pigswill's statement to mean that he was pop rushing the warriors, but you seem to have meant warfare, which isn't the point of this exercise.
