Just get rid of all the barracks and replace it with one.
As you upgrade the barrack, it unlocks new troops, but the size que is the same.
That's essentially what SC did with the new and improved training setup
I just soon have the old way back anyway. That way i can feed mouths as I'm building my own troops. Waiting for 2 golems to train and not being able to train anything else is a waste of 4 barracks
