I quite like the Barbarian subclass updates, though I still think fire damage for a desert barbarian feels forced. I get that causing exhaustion would be overpowered, but deserts aren’t full of fire, they’re just dry, and they’re cold a good half of the time. Ah, well.
Removing the limit on the Cavalier’s mark is great. Hook that 4e Defender class action right to my veins.
The drunken monk is a complete mess, like I says. It stil (IMO correctly) says it’s about imitating the movements of “the intoxicated” not about actually being drunk, but then for some reason decides it needs magic potions… which have nothing to do with being drunk anyway, so why are they here?
Oathbreaker is still trying to be an antipaladin when it should be a fallen paladin. Take all the undead, fiend, necrotic damage stuff, put it in its own Oath of the Balckguard subclass, and bring back the old UA Oath of Conquest mechanics for a proper Oathbreaker. Give the Blackguard the tenants about fear and domination, and give the Oathbreaker tenants about doing what must be done at any cost, even your own honor. Oathbreakers should be anti-heroes, with Blackguards as the full-on villains.
