Hate to point out you never could march troops while under protection. Instead this new addition of command legion now gives you a lot of protection and in my humble opinion makes warfare just a numbers game of who has a bigger army and a bit dull.
Instead of the challenge of avoiding enemies to get your army where you want it and ready and takes a bit away from cooperation of city members. As you said a sorry state of affairs indeed when we need to continue to add protection for people.
