If we get a pure Garlean job class...

Edit: Lmao, I forgot to add Magitek to my title!

What I meant to ask is "If we get a pure Magitek Garlean class..."

What would you want it to be?

For myself, it'd be either Gaius' gunblade and overall fighting style or Nero's gunhammer.

A jobclass representing Rihtahtyn sas Arvina from Cape Westwind. The guy using 2 shields.

"Do you require healing?"

I've been begging for him as a Job for us since ARR lol.

Magitek jobs in general would be fun. Can easily explain why we would use Magitek when we have Aether as something sort of similar to Thancred and player Gunblades in general.
Thancred can be a Gunbreaker because he gets ammo from elsewhere.
We as Gunbreakers make our own ammo.
We would just be taking Magitek and fueling it with our own Aether in place of Ceruleum and prefabricated ammo.

Reaper being not only a Garlean job but a Garlean job with a Soulcrystal leaves the door wide open for us to get the Magitek jobs from those notable Garlean characters.
Mild retcon to have them quietly carrying Soulcrystals that we end up in possession of.
Why would current content drop Magitek weapons? Canonize it as the Ironworks as helping the WoL make gear for them to adventure with.

Didn't we just get Reaper?

Lol, I meant to add "Magitek" in my title. xD

[NegativeS]

I would love a giant hammer, or some kind of explosives user.

[Feronar]

We have the Reaper. It is explicitly stated as having been invented by the Garleans' ancestors.

UPDATE after OP clarified to mean Magitek:
I would like to see a Commando (CMD), armed with an assault cannon or machine gun, kind of a cross between Laguna from FF8, the Republic Commando job from SWTOR, and modern real-world special forces. They could wear Scouting gear, like the rogue/ninja.

I'd rather just get the third eye as a glamour item and call it a day. Besides, as others have said, we already have Reaper.

How about a class that lets you pilot a small magitek vehicle? Like a mecha or those tiny 1 man helicopters the Garleans sometimes used?

It's a shame that you can't wield Regula's huge gunblade. That being said, it would be cool if Gunbreakers could summon that Ceruleum lion that Regula had.
