personally I would scrape both armor and weapon proficiency categories.personally i thought too many classes got full martial proficiency in 5e, or at least 'proficiency in the one martial weapon they'd ever really want to use in the first place'
We now have mastery for martials, so simple/martial weapon proficiency is not needed.
And with 5E weapons table it has no logic from the start.
Mastery, Extra attack(s), fighting styles, attack riders, investment in STR and/or DEX is enough to separate martial from nonmartial character.
heavy armors introduced min STR for some armors.
Just make that across the board for all armors and you do not need armor proficiency.
You can take (heavy) armor mastery feat if you want to be good at using armor.
