Casters Next

[GrimGale]

BLM

Thunder V?



SMN

Fester II?



RDM

Thorn vine whip attack

[Ggwppino]

unlike the sch, the smn is not accompanied by any pets

[VentVanitas]

the attack that the Monk showcased appears to be a visual upgrade to a combo skill, my money's on either Twin Snakes or Snap Punch.

[Arkdra]

It looks like a lightning skill so I'd bet on it being ramuh based and the shot doesn't have the pet because it's done in that weird interim period where the summon is disappearing and carbuncle is reappearing on purpose to hide ramuh.

If you look in the background, just before the SMN explosion, you can see MNK perform another attack, which appears to be an uppercut with a dragon. I could make a statement that that is a Dragon Kick upgrade, which then leaves the tiger as either True Strike or Twin Snakes.

Either way, it looks like MNK is finally getting some visual upgrades.

My predictions:
DRG- It's getting fully reworked so no clue. Possibly a stardiver followup or another firstminds focus spender.
DNC- Upgraded saber dance
MNK- Snap punch or twin snakes upgrade
SAM- I watched this at .25 speed. Kaiten is back!!!!!! The new skill i suspect is something like an upgraded tenka goken. Perhaps kaiten is now a skill that just empowers iajutsu's and this is what empowered TG looks like? Also worth noting the samurai immediately follows up with Gekko so this seeminly doesn't break combos. EDIT: Kaiten is not back, it's ikishoten. So nvm, i have no idea what SAM's new skill is.
NIN- Hellfrog upgrade.
MCH- I'm betting on an upgraded drill of some sort. I doubt this is a new skill. You also see the MCH use chainsaw as the camera is panning over.
BRD- Given the absence of a yellow/blue flash this may be a cast? Perhaps an aoe wanderer's minuet spender?
RPR- You know how during enshroud you use 2 GCD's and follow it up with an OGCD? Same concept but for communio. If you play it back really slowly you can see communio's particles on the mob before this animation plays.
BLM- Seems to just be a thunder upgrade. Worth noting no AF or UI orbs orbiting the black mage.
SMN- Similar animation and sfx as fester but with a thunder effect. Possibly this is what fester becomes when you summon Ramuh? Could just be a fester upgrade.
RDM- Given the blue flash this is an OGCD. Could be something usable only after embolden but I doubt that. Probably a visual upgrade to contre sixte.

The evidence that the new BRD skill shown in the benchmark might have a cast time has me super excited, however the BRD is also shown using instant cast Burst Shots, and to that I say do not be afraid to add a walking cast to that skill. It will be worth it. Trust.

[Sequora]

Summoner is more than likely using a Ramuh skill.

maybe ramuh, shiva, leviathan after phoenix? but also fester and painflare have lightning in them already so it could just be an upgrade for one of those.
