Something got me wondering real quick.
In most movies, comics, and cartoons (western and anime), warriors tend to have a decent punch and kick.
I was thinking, should every warriror class be given a dice for their unarmed strike? Nothing crazy. a 1d4.
It's not a major combat boost. Not even a minor one. But it's simple and allows martial classes to punch and slam do. Since Feats are currently mandatory, feats can be used to upgrade this. Tavern Brawler would still be worth getting. Same with Unarmed Fighting Fighting Style.
Monks would still be unique as the only ones that can US with DEX, bonus action US, and have an automatically upgrading US.
