Another melee that is dex based. With reaper coming in Endwalker it appears now that only NIN will be the one in the corner with no one to share gear with. Have them use something like Tonfa or a Bo-Staff.

Outside of that 1 thing I've noticed in terms of in game content.

Gambler - Ranged DPS using thrown weapons themed after playing cards, darts, dice. Skills with RNG components to them. Job build focus IMO should be more about being fun to play with the RNG elements and less about how they can make it fit in any kind of min/max meta. It would be nice to have a job that was at least somewhat unpredictable.
Puppetmaster - This might only work as a limited job of sorts tbh. I'd go for an idea theme based on how it was implemented in FFXI. However instead of having the player character actually fight, use the mainhand slot for interface or controller options to control the automation or perform maintenance commands on it. The automation itself is a base frame that upgrades as the PUP levels up allowing more components to be installed which allow use of it's equivalent of skills and abilities and also impacts it's stats allowing it to be customized into a sort of role. Parts can be found, purchased from NPCs, crafted, or obtained from PUP quests.
