Well....
Red Mage as any role (which is more demanded the Samurai)
Dancer as any role using either a bo staff or dual-wielding swords
Morpher from FFTA or anything with a transformation-type skillset
Chemist, either standalone or merged with some sort of artillery-based job
Viking or anything that would use at least one hammer
Beastmaster, dual-wielding clubs and thematically less "Tamer" and more Tarzan
Anything based off of Charioteer from Bravely Second (QUAD-WIELD BABY!!)
Merchant as a caster or ranged DPS that relies on indirect attacks and a "wealth" themed secondary resource
Puppetmaster remade as a ranged DPS and having the majority of its skills being nothing but pet commands
Any other sort of true caster tank (as opposed to Dark Knight, the tin can with magic tricks)
Any other sort of STR- or DEX-based healer (as opposed to standard INT-based healer)
Any job that fights while on some sort of vehicle or mount treated as a pet
Need I go on?
Also the main reason why I find Samurai uninteresting is that the main reason why people seem to want it is either because of this whole notion that we need a sword-based DPS job (which I don't necessarily disagree with, but don't believe it should be Samurai) or because of people who want Samurai just like how it was in XI, which won't work on a practical level due to systems working completely different between those two games (otherwise there'd be less people going on about how bad Summoner is in this game because summons are nowhere near as impressive or valuable in XIV).
There's also the question of how would it be distinguished from Ninja if Samurai would be a DPS or Dark Knight if Samurai would be a tank. "I want a tank in heavy armor with a big sword that relies on parry". Uh, yeah, we have that, it's called Dark Knight, and it's one of the main reasons why we know that parry is almost a negative stat in terms of itemization. "I want this Japanese-theme job as a DPS". Like Ninja, which already kinda works? There needs to be something more that sets it apart from jobs like Ninja or Dark Knight, something to make it stand out and feel both special and unique compared to the other jobs in its given role and grant it a reason to exist in the game. So far, I have yet to see such a reason. I would admit that some have gotten close, including the OP of this thread, but still not there yet.
