Just a very minor suggestion here, though I will include this in the Bug section as well, since some portions are technically "bugs".

Currently, there's no way to play an Unarmed character other than Monks when they get implemented. However in tabletop, Barbarians can still apply their Rage damage to Unarmed Strikes. They technically deal 1 damage, but that 1 damage is treated as a D1, as confirmed by Jeremy Crawford and the PHB's wording.
Technically, it should be working as follows:
1D1 + 3 (16 Strength) +2 Rage bonus
6 Damage per hit

Obviously not the ideal way to play, but thematic at the very least.

In addition, Frenzied Strike currently states "As a bonus action, make a melee attack with your equipped weapon, dealing Weapon Damage slashing damage.". Would love to see this say "Make a melee attack", rather than specify you must have a weapon equipped.
Tabletop once again states "Starting when you choose this path at 3rd level, you can go into a frenzy when you rage. If you do so, for the duration of your rage you can make a single melee weapon attack as a bonus action on each of your turns after this one."
A melee weapon attack does include Unarmed Attacks, as seen here: https://twitter.com/jeremyecrawford/status/1088200198814232577?lang=en

On top of this, seeing as the Berserker already has the trait of "you deal extra damage with improvised weapons" and Tavern Brawler includes proficiency with said improvised weapons (Which I don't believe makes a huge difference in BG3), I would love to see Tavern Brawler increase Unarmed Strike damage to possibly a D6 rather than a D4. Then, you could play something along the lines of the following:
Unarmed Attack
1D6 +3 + 2 = 1D6+5 damage per hit

Alternatively, some gauntlets that increase Unarmed damage would be nice, but I'm hoping for something more like the above to make it part of the "base" part of the character, rather than an item.

Sorry for the long post! Just very enthusiastic about being able to angrily punch and throw some goblins around!
