Removing CS values won't do anything to reduce blob armies. Instead of comparing CS, they'll compare raw numbers, but they'll treat the numbers just the same. In fact I'd wager it would only increase trench warfare since both sides will just recruit as many men as possible to improve their odds, but at the same time they will be hesitant to attack since they don't know exactly how strong their enemy is, and you'll just end up with huge armies staring at each other and not moving.
