MCH with flamethrower, I'm looking forward to see more machines or gadgets in the MCH skillset.

The gloomy violet spell for BLM could perfectly be Dark, dealing unaspected damage. If they also added Quake, that'd ice the cake. And a finishing spell like Death/doom
Though not an insta-kill ability, but a high-damage abiity only usable on enemies below 20%. Or a high damage tick that triggers after a countdown ends, like the current Doom
would be the cherry on top of the fantasy class.
And as a hidden desire, changing the current CC spell to be Toad would make it a bit more iconic rather than having both BLM and WHM with Sleep spells


Also, I love that we SCH get some love pet management that can go further than just killing it. Also, I'm hoping WHM new skill could be the buff-type spell many asked for.

At last, Eureka doesn't look as I imagined but it doesn't look bad though.
