The newer Unearthed Arcana for Clerics, Druids, and Wizards seems to be causing a bit of a stir. I figured that I would put in my thoughts for these just as a quick post.

Cleric - Twilight Domain: I like the broad idea for the subclass, but the implementation of the abilities seem unfocused and poorly thought out. I love the idea of a cleric who worships a god of dreams, but they should be more of a caster type of cleric in the same vein the Knowledge and Light domains are. The armor and weapon proficiency makes no sense to me personally. I say base the abilities and features around dreams, sleeping, and things like that. 

Druid - Circle of Wildfire: I think this one is legitimately a fun idea as well. None of the abilities seem too mismatched like the clerics, just unrefined. I hope to see this come to a source book soon.

Wizard - School of Onomancy: The lore with this one is incredible. I love the idea of suddenly, a name can mean just as much to an adventuring party. It gives a whole new way for a wizard to play their class. I can't say too much for the abilities, but I don't think any of them are too broken. I love the flavor enough where I absolutely want to make a wizard who is a paranoid wreck because of something or someone having learned his name, so no he only goes by the name of "Wizard" or maybe whatever day it is.

If you guys want to chime in with your thoughts on these new UA's, then feel free to respond. I love how we are getting so many more lately. It makes me very excited.

I think some of the twilight domain's features should have their ranges set/reduced a bit. Other than that, as a cleric that is dedicated to fighting creatures of the night to protect resting townsfolk, I think it's well designed.

I like the druid's new little fire soul. I like that they are giving druids something else to do with their wild shape that is more unique.

My only complaint about onomancy, is it needs just one or two more metamagics that can be used on allies. Otherwise it is a cool and unique subclass.

In terms of themes, I love them. This might finally be a Druid Subclass to convince me to make a primarily Druid character, I always like the idea of Twilight and Monster Hunting, and the Wizard subclass is the return of Truenaming. I still need some time to figure out mechanics more to develop a complete opinion, but:

• I like the idea of Vigilant Blessing, Initiative has been kind of static for most of 5e so this is fresh.
• Twilight Sanctuary is something that moves with you, so it's kind of like the Paladin Aura Spells with refreshing Temporary Hit Points, which is pretty neat.
• Midnight Shroud might be nice, but it looks boring and too specific to me for a 17th level feature.
• Wildfire Spirit is cool and another use of Wildshape without changing yourself into a beast, a rare thing and something I want since I would prefer to make a Druid that doesn't transform. Furthermore, Enhance Bond allows you to do some Familiar strats with a Druid, but it also works with non-Touch Spells making it better.
• The Ability to Bless or Bane a creature without a Spell Slot is really nice, especially since you only need to know the truename of one of the targets. Though this is still limited, but nonetheless.
• Resonant Utterance is basically a type of Metamagic available for Wizards, but requires the truename.
• Relentless Naming is a nice way to avoid Resistances and Immunities, but a player might end up relying on it too much. If a creature pops up that has Resistance to Force or Psychic Damage, especially if their Humanoid, the player may end up hurting their own damage potential.
