here's this updates tier list, I can't rate the chapter 2 unit skill buffs because I haven't unlocked the sisters condition and Cervas conditions. I'll probably add them during the next update though.
Ur-M:A 6.5/10
Pros: can tank some magic, speedy on player phase
cons: can't tank all that well on enemy phase
She's a solid enough unit who can tank fire and ice magic attacks and offensively good on player phase but struggles beyond that. Nothing wrong with her but nothing notable to make her too unique.
Gelat: 3/10
Pros: High stats, unbreakable personal weapons, powerful personal weapons
Cons: goes berserk randomly and all the Pros can be turned on you
She's a very strong unit but her berserk can be annoying and screw you over. I wouldn't even say she's an okay filler option because Cervas and Paola have defensive utility and doesn't turn on you.
Oklys: 10/10
Pros: Dancer
Cons: frail
She's your dancer and she's great. Letting your best unit do an action twice is invaluable. Not much to say except at worst she's filler and at her best she's basically your best unit.
Frida: 9/10
Pros: Speedy, nuclear damage
Cons: Frail?
She's basically Viske but uses axes and doesn't need to crit. Her being speedy and her skill buffing her attack makes her do absurd damage and she reliably doubles. She's a little frail but not paper frail and can take a hit when needed.
Zest: 7/10
Pros: Tanky, potentially do high damage with her skill
Cons: Slow, Skill potentially decreases her damage output
Zest is unique because her damage is unreliable but something that is reliable with her is her defense, which is oddly high. Also I don't know if this is intentional, because she's drunk, but for some reason when promoted to paladin she has very low move. Don't drink and ride!
Qilph: 9.5/10
Pros:Fast, High res, flies
Cons: not physically strong
Qilph is your first flier (unless you promote Jurrisa) and she leaves a pretty good impression. Being able to not be bothered by terrain and not being insanely frail is nice utility. Along with just being able to transport units is nice. While she isn't an offensive juggernaut like Viske and Frida her useful utility and good enough attack to destroy mages and other weaker enemies make her great.
Marin: 10.5/10
Pros: Fast, bulky, good personal weapon, solid skill, flies, good base stats
Cons: weak to arrows???
Marin is genuinely insane, she basically has no flaws. She flies, she has good strength to destroy anything, her personal weapon just lets her charge into hordes of enemies and heal off the damage, and her skill just makes her stronger after one kill. This is fe6 Melady but on steroids. Just keep her away from arrows?
I like the new update but I only have 1 criticism in that I feel like the Marin boss fight is too hard, All her positive traits basically are in the boss battle, with addition to her having no weakness. None of my units could do any meaning full damage, and the ones that could had shaky accuracy like Frida and Marin just healed off the damage with her personal and ultimately I just used test buster.
