So it is alright for spellcasters to have more and more classes but martial characters can live with the small amount of nerd revenge design that gets thrown their way. I also find it disgusting that people actively campaign for the exclusion of something others want and that they can choose to ignore. Great so your enjoyment must come at the expense of others.I am missing the "I am a player/DM of 5e and actively do not want WOTC to create a warlord class".
No more dissection of the warrior archetype into smaller and smaller chunks. Warlord is something characters can do at high level. As such it should be handled outside the class structure--get a castle? get an army. Run around conquering things and warlord-ing it up.
EDIT: voted "don't care" but that is a lie. I do care. I actively don't want a warlord class.
