Unearthed Arcana makes an unexpected return (the last one was back in May) with a three-page PDF containing two subclasses -- Path of the Wild Soul for the barbarian, and Way of the Astral Self for the monk.
Not to belittle the setting by any means, but Eberron has always given me an Anime vibe (in a good way). Very Full Metal Alchemist.e
How about the Smard? It's a Smug Bard, that takes an Oath to, um, Smite evildoers with his lute?
No?
How about the Healing Warlock, which ... oh, wait ....
Sometimes it feels like they just create subclasses just to cover every possible combination of fluff/lore and mechanics. Reminds me when you started seeing CHA based fighters.
"Well, we know STR and DEX can impact the ability for a fighter to be effective in combat because those tie together in a logical way. But that's not enough. We should have fighters where they add their CHA bonus to hit and damage because good looks and witty words make sharper blades or something! And one where they add WIS bonus! And one where they add INT bonus! Because reasons!"
Personally I'm really into that Barbarian's mechanics, although the Feywild flavor doesn't fit well. It seems more like a fit for Limbo or the Elemental Chaos.
I will say that they should try converting some 4E Paragon Path concepts, but I appreciate that they're experimenting.
The Astral Monk.
Cool concept. It has some nice flavor and interesting features, and it doesn't seem too OP. I can easily see a Githzerai Monk with this tradition.
