Arguably, Machinist was always "Tools first, guns second" because Edgar never used a gun yet almost every single Tool he used has been lifted for Machinist to use (only Noiseblaster, Flash, and Debilitator are unaccounted for). Even with regards to Mustadio, its job's main gimmick was the Snipe skills with Head Graze and Foot Graze effectively being Arm Shot and Leg Shot (only Seal Evil was left out) with guns not being exclusive to his job. Not to say there shouldn't be a primarily gun skill using job ala Musketeer/Gunner/Corsair/Cannoneer/etc, but rather I get why FF14 Machinist leans more on Tools and debuffs (including Dismantle) than full gunplay.

But speaking of axed content from 1.0, the Pugilists Guild's attached "Platinum Mirage" was probably going to be the game's "mini-game hub" in Ul'dah (complete with its own dice signage) but was likely replaced by the Gold Saucer in function while being made into a separate zone.
