And so what has he done? He's released new fighter sublclass playtest materials where the maneuvers are just pre-selected. What he hasn't done is redo the fighter.It was a personal comment on the design choice that is made BUT the train has not left, a martial class designed to be advanced could still be designed. Personally I think that whilst the Battlemaster is mechanccaly effective it was a half ass attempt to appease those who wanted an advanced martial character. Another issue I have with fighter design is shared with the designer which is that there is a mish mash of mechanics that tell no story or flavour (Mike Mearls has spoken on this several times). I believe that a subclass should have mechanics that point to story or flavour and that is by far and wide one of the fighters failures. Mind you a lot of this is said through my personal lense which wants the fighter to be great and believes that aside from the edition that shall not be mentioned for 40 years fighter were designed by nerds who suffered having their heads flushed by jocks all their life thus fighter design is largely nerd revenge fantasy constrained by D&D tradition and grognard resistance to change. So when I discuss matial classes I am willing to admit a bias of believing that it suffers from unfair design restraints both mechanical and philosophical.
I'd also like to read his issues with what you describe, in his own words, if you have a link. Thanks in advance.
