Info is out for new JP event that's coming tonight.
CG Jake
His basic damage loop is Assault (Fire, Ice, Electro, Light) -> Last Shot or Fatal Barrage. Last Shot is ST 1 hit 275% with 50% ITD while Fatal Barrage is AoE 8-hit 200% with 50% ITD. It gives him a lot of versatility in regards to whether he needs to do ST or AOE damage and he's not bound by any single element because the duration of his Assaults are only 2 turns.
He also has a 3 turn -45% ATK/MAG Break that leads into a 3 Turn -45% DEF/SPR break that then leads into his Last Shot and Fatal Barrage. Very good on the case you need him to be your breaker and have elemental weapons equipped as he can then participate with your chainers after he's done his job.
His LB is 720% with 50% ITD which is super strong. Major downsides is that it's 40 LB crystals and it causes a -99% ATK/DEF buff to Jake. However, he has an ability called Force Charge that prevents the attack down and charges 20 LB crystals. That becomes Cool Force which charges another 20 LB Crystals and gives him a 3 turn 100% LB fill rate up. So he only really has to worry about the -99% DEF there, lol.
He also gets Dual-Wield which means he's free to use whatever passives he can which he'll need because he only gets 50% attack with Gun on that front.
Basically, Jake is a super upgraded version of Onion Knight. He has innate DW, has multi-element coverage without being forced to use a specific weapon or a buff for a long period like Balthier. He can do ST damage if necessary but his big thing is AOE damage with Fatal Barrage. He also has be a breaker if you need him to be and still output damage.
Emperor Shiera
Basically a Fire Orlandu (enhanced) with more utility but looks like Emperor Sohze and has a few of his trademark skills, lol. He actually has a little less in his mods overall but it's pretty damn close. Big thing that separates him from Aileen and Orlandu though is that he has an AOE attack that is strong. Pairing him with Jake could be a serious wrecking crew if the data matches up nicely. He even has Dragon Killer and Plant Killer too.
TMR is crazy good as well. 20% Fire Resist, 50% Attack, and 10% HP when equipped with a Sword and Light Armor.
Ozetta
Basically a mini-Wilhelm? She has a new skill that Merc Ramza also has with Yell where you have a 100% rate to cover a character you pick which is pretty solid, I think.
Riley
TM Fodder for now.
Emilia
Knife version of Amelia which is to be expected. Seems fairly decent and you get her free, I think, which is sick.
Enhancements:
Balthier
Pretty straightforward enhancements, He'll be very strong and much more useful. Lethal shot is 300% with 50% ITD. That brings up his overall damage in the loop with Finishing Blow. His Thunder element imperil is -75% which is pretty solid.
Ashe
Pretty junky enhancements.
Rasler
Makes his tanking abilities a little stronger but not by much. 3 Turn 40% chance to cover all is not great and his defense upgrades aren't massive.
Vaan
Increase chance to get his Counter Break and a buff to his chain attack. He basically has Zdiane-tier enhancements which are pretty good, I think. If you have the stones but not the chainers, he could be a decent choice.
Mercenary Ramza
Got buffs across the board. Whether or not he fits with current char usage, remains to be seen though. His Yell has the new cover variant that Ozetta has which might be interesting depending on the exact mechanics of it. -60% breaks are nice as well but it's locked behind Sword of Justice which means heh as to use it every turn to get the enhanced ones. At least it saves us stones. He also gets a free 15% to all elemental resists which is sick
Knight Delita
Damage buff on Bouryaku no Ken is solid and makes it decent for chain finishing, I guess. Not sure why they didn't buff his chain skill...
Orran
Decent enhancements I guess but still sorta sucks overall. Pretty niche usage.
Meliadoul
Basically got what I expected, -50% on her status debuffs. Her ST DEF/SPR buff got a 15% damage reduction and Regen buff too which isn't shabby.
Balthier has always been a few steps behind other top tier damage dealer because the only way to boost his atk is through the use of multiple blade masteries and a maid apron, and even with all that he is still going to have less atk than your fully decked out OK or Aileens. Lethal shot -> finishing blow loop is nice but honestly even before these enhancements I think I still got to pull off at least one finishing blow every 2-3 rounds. It just feels like a very slight improvement to me. His thunder imperil seems good at first but really in this day and age Sakura totally blows him (or anyone else for that matter) out of the water when it comes to striking with thunder. Her own counter thunder imperil does 100% imperil without any enhancment too!
Ramza would have been nice if his Yell covers more than a single Ally. Wishful thinking I know. He could still be useful though if his breaks do -60% or more after 正義の剣. We'll see.
The problem right now is that everyone using AOE Cover tanks which makes these on counter abilities weaker as a result. Being able to bring Finishing Blow is a pretty big buff, I think. The damage to Lethal Shot +2 also went up as well which makes the loop stronger.
Balthier should be able to get close to cap nowadays, can't it? He can wield spears so.
Dragon's Beard/Acrturus
Passives - 80% (30% ATK, 50% with Gun)
Genji Glove - 10%
Spear Mastery x 4 - 200%
is 290% status boosts right there. You can then slap on flat attack bonus equipment from there. You'd lose out in other areas like HP/DEF and the like but his attack should be pretty good anyway.
His Thunder Imperil is really nice as well because while Sakura can get a 100%, it's on counter. If you're using Mystair for the cover, Sakura won't get chances to activate it and it's stil only a chance if she does get hit. For some strategies, you can't rely on that.
Ramza's breaks are 60% according to reddit. His Yell Cover probably isn't AOE but guaranteed single target cover.
