Humans have the most diverse stat line ups and bonus skill points, free trait along with potential divine eyes and bonus skill pool. The skill slot bonus has diminished slightly but the amount of saved stat points is still quite notable despite the recent addition of skill slots. They're fine as is, they're average to good and can fit multiple builds.

Umbral, I'd honestly rather not have this as hard investing into RES will net you more dark attack than what's suggested. Zerg's idea of it being a trait would work fine. In terms of fade out, it's honestly just kind of an okay skill? It's a better disengage unless you value the bonus HP/movement from disengage more. Give it sneak back, sure; why not, it's flavorful and synergizes with spellthief.

Omina as Zerg stated, should get more benefit from SAN, though I think more debuffs and trickery would be cool; something akin to an inverse fortune cookie like what Redtails have would be pretty sick flavor.

Vampires... I think conceptually they're among the most flavorful races in the game and have a lot of interesting things about them that are woefully underutilized and underpowered. Activating your crest is a pain in the ass, life drain and banquet are both skills you generally wouldn't use under most circumstances and the reward is a bunch of plain stats which frankly do little if you even use those stats to begin with.

In my honest opinion, crest should be changed to bonus SWA/Hit/Elemental ATK(or only dark attack) and then have a flavorful trait like 'Bat Form' which increases your evade by a set value and the alternative would be 'Ghoul' which increases your armor/magic armor instead (or instead just use the traits for Lunar but that's lame). Bat could give you Bat wings while Ghoul gives you access to more pale skin tones. On top of that, it'd be cool if Crest could activate off of any blood-related ability, such as vampiric weapons, claret, blood magic and so forth or just a few of these examples if that's a bit much. I think the penalty for crest burnout should be mostly removed if this were the way to go, or heavily diminished. Lunar Lunatism could double or triple the bonus granted by Crest so playing into your true nature as a vampire would be a lot more rewarding. Just food for thought, though; I do think regular stats are pretty bad to have, especially when they're so miniscule and all over the place + having a drawback for losing crest.

Mechs... I'm of the mind that Agile is pretty much the only worthwhile one, but Standard does have some value as a budget armor with good stats attached to it. Raid and Cabal definitely could use some love, the 'Scan' idea, Zerg proposed for Cabal is brilliant and I think it adds a flavorful niche to the race. Raid Revolver could honestly get skill scaling back and be more or less fine.

Hyattr, yeah sure; not much to really say here.

Wild Elf is a bit underrated although I wouldn't say they're one of the better races. As Zerg mentioned, they get a nice bonus to hit on instruments; only issue is that this is pretty niche as a majority of instruments aren't the greatest attacking tools. They have solid stats and free hit, but that's mostly it beyond the tribal bonuses. Hard to really think of a buff for this race when they're very middling in terms of strengths.
