The Drunken Master I'm a bit disappointed with, though I can't completely put my finger on why. Gun to my head I think it'd be Tipsy Sway being once per short/long rest rather than just using your reaction or something. It's a minor thing to be sure, but it just leaves me a bit less interested in the subclass. There's probably more to it, but like I said it's hard to put my finger on.
I actually quite like the Oath of Redemption, and that's surprising to me because typically I don't go in the for the "pacifist" type classes. I like this though and maybe it's the simple fact that it points out: expect to fail. There's something about how it acknowledges how tough this path is and that these Paladins shouldn't be naive and should expect to fail in redeeming their foes. It's a small thing and it's a "fluff" thing rather than a mechanical one, but for some reason it makes a difference to how I take it. Mechanically I actually like everything and don't mind Armor of Peace being 16 + uncapped dexterity modifier, even if it'll probably a popular dip option for some classes. Regardless, I'd play one of these and I usually don't buy in on these kinds of subclasses.
And the Ranger... indifferent. It's not bad, it essentially seems like taking hunters mark and making it the focus of the subclass. It's not bad, I don't think, it just doesn't do as much for me as say the Primeval Guardian... that one I saw and immediately said "Yes! I'd play that!" This one not so much.
