This post is more about what power level do you like in your games for martials and what do you do to make the feel the way taht feels good according to that.
In my case my biggest problem is how unidimensional they are, so advanced 5e has done the thing for me. I think that if we play at level 20 i would do some hombrew to push them even further but i like how many options they have.
I of the opinion that low level martials are cool but lacking in options and level 9+ martial characters are underpowered AF. That has to do tht as I subjectively understand dnd everything is made by magic, so the limit of physical feats should be as magic, like lifting tons or demolishing buildings with blows.
So, do you like martials in 5e or would you rather them to fulfill a different fantasy?
It’s not about breaking the game. To match a caster in damage you have to build a munchkin martial, and even so the caster will still be more versatile.
Thankfully the Rules Lawyer has an entire video about this that captures my view so I don’t have to write an entire post about it.
