Did this with shadowbringers, thought it'd be fun to do it again.
Warrior
-Do not fear. Defiance is still here.
-Infuriate
-Looks like somebody joined the 2 charge, 30s 200 potency no resource dash ability!
-AoE combo in single target.
-Another dash!
-Nascent Cyclone.
-Smack.
-NOW PUNCH PUNCH PUNCH!
-Punch, punch, punch!
-Smack
-Nascent ANNNNNGER
-Smack
-Decimate is still here.
-Dash thrice!
-Golf Swing
-Waste a gcd of Inner Release. Some things never change.
-Fell Cleave. Yawn. Fell Cleave. Fell Cleave.
-Fell OH HEY THERE.
Flashy. Not much to say here, seems straight forward.
Dark Knight
-Fear not. Grit is still here.
-So is Abyssal Drain.
-Plunge
-Lets triple weave Blood Weapon for good measure.
-Salted Earth is still here!
-Hope you weren't expecting a new combo.
-Carbonated Earth
-The Classic Knight
-I WILL BE YOUR SHIELD. 'Wait, isn't your shield a manifestation of your inner self realizing that despite everything, every regret, every pain taken, that you still love yourself, and that gives you the strength to push on?' Please don't make this awkward.
-FRAY. HELP ME GET OUT OF THIS AWKWARD SITUATION.
-Shit I forgot to put up my damage buff.
-Flood decoupled on CD, or an ability chained from Edge. Gee, I wonder which new ability the Shadow learns.
-Hey you loved this moment from the last trailer. Why aren't you cheering now?
Salted Earth getting some relevance back is okay. Feels like it all hinges on how the Newest Knight works and whether that feeds back into the kit.
-Post thought. The "New Flood" has the yellow swirl of a weaponskill, while old Flood is still present near the end. Weird.
Gunbreaker
-Be not afraid. Royal Guard is still here.
-3 charges, lightning, dash. The best opener.
-Smack smack, bigger smacksmacksmack, smack.
-FLY INTO THE DANGER ZOOOONE
-Heart of Stoneskin 2.
-Circle smacks.
-Technically circle smacks.
-FIRE CROSS
Like the warrior. Straight forward. The 2 cartridge spender might be interesting, though, it is possible that the way it lines up is that it just keeps the straight forward rotation people like despite having more cartridges entering the action economy.
Poster Boy
-Steel thy heart. Iron Will is still here.
-Dash smack smack smack.
-Spirits Within Upgrade. Could it be...will you no longer be punished for being below full HP?
-Shell2Tron
-You shall not pass.
-Reqqy Cat.
-Better rotate through every spell so you know they're still there. Don't ask where Royal Authority is.
-Shellstab still there.
-Oh, it gets another stab, neat.
-Oh, it's still goi-
-DEMACIIIIIIIIIIIIIIIIAAAAAAAAAAAAAAAAAAAAAAAAAA
Okay, well. That was fun. At this point, avoiding the poster boy curse seems cause enough to celebrate.
