So, one who makes a huge t1 army, and one makes a lot of turrets. Is the t1 army immediately doomed? Well, you can't use it effectively in t1 rush, unless you see an opening, sure. However, those turrets can't move for the rest of the game. So, if 1 were to hold onto the t1 army and wait till t2, they can rush t2 just about as fast. Then, get long range units, and destroy the turrets with those, then you have an effective t1 army to swarm with after just 3-4 units open up the front. I believe they do not underrange pelters by very far either. Besides, that army can still be used as turrets with acceptable losses. Just saying, I think people underrate them, aside from the fact walls and turrets can use some kind of a rebalance.
