I am a bit despondent about success at properly enriching the 5e fighter in a manner It seems like it ought to be. 5e stripped out a lot of handles , like that charge and marking. I looked at the Cavalier closer and it looks like its not nearly as capable of defender in many ways even at high level as a level 1 4e fighter. For example you know how come and get it is cool? Look at this one charge into a bunch of enemies and mark all of them around you. There is no real way to even give the Cavalier something simple like this.
