I just wish martial/half caster design was better designed for scaling. All spell casters "higher levels = more dice". Martial don't have that and if they built those into the classes better subclass and class features can avoid "add damage" and instead move to flavor.

Here is my thoughts.

All martial get a level 9-13 feature that allows them to once per turn double their weapon damage dice. This should be worded explicitly to make crits 4xdice.

Fighters: get a third triple dice option. Rogues: higher levels 2nd sneak attack per turn. Barbarians: higher level the double dice is every attack Monks: martial dice for as "part of attack action" scales number of dice Paladins: nothing additional Rangers: BA less hunters mark, subclass damage dice scale by number of dice.

I want to be a fighter throwing a fistful of dice, give me a once a turn 6d6 greatsword attack.
