What do you guys think of the idea of adding new Soul Crystals to further add depth to existing classes? For example, the Arcanist class is able to choose between two jobs with two distinct roles: Summoner as a DPS and Scholar as a Healer. This would allow players to try out more roles in the game without being required to level a character from scratch.
Here are some extra jobs I had in mind for currently existing classes that I believe could fit in very well:
Gladiator (Tank) → Swordmaster (Melee DPS)
I'm sure that there are some people out there who initially picked a Gladiator thinking it could DPS only to end up as a Paladin which is a Tank. So how about allowing Gladiators to dual-wield swords like Raubahn by allowing them to become a Swordmaster or Sword Saint instead? Being able to dual-wield would expand the meaning of what it is like to actually be a gritty fighter in the Colosseum rather than a royal guard.
Lancer (Melee DPS) → Templar (Tank)
Using Holy Magic to enhance their defenses, the Lancer can take on the role of a Templar instead of a Dragoon. Its lore can easily be tied to the Ishgardian Orthodox Church and could get an in-depth class quest surrounding the Heaven's Ward. I personally feel like the addition of the Templar job would be the most seamless one compared to the other jobs I mention in this post.
Rogue (Melee DPS) → Corsair (Physical Ranged DPS)
If the Ninja is a stronger version of the Rogue in the Far East then what would be its equivalent in Eorzea? Limsa Lominsa is full of Pirates and the Corsair would be a fitting development for the Rogue. The Corsair could be unique in that they dual wield both a melee weapon (either a cutlass or dagger) and a pistol. It's not often that we get a ranged/melee hybrid class.
For the more controversial job ideas that I have:
Archer (Physical Ranged DPS) → Ranger (Physical Ranged DPS)
Archer (Physical Ranged DPS) → Bard (Magical Ranged DPS)
This is very controversial since it talks about altering an already existing job so I can understand why you would disagree with this and it's very understandable if you do. Traditionally Bard has always taken on a more supporting role while the Ranger is the traditional damage dealing marksman. Since they share a level then it wouldn't be too bad to change the role of the Bard a bit to be more supportive and to use some magic in their arsenal.
Pugilist (Melee DPS) → Puppetmaster (Tank)
Ora ora ora ora ora ora ora ora!!! Muda Muda Muda Muda Muda Muda Muda! ゴゴゴ... Yes, I am a JoJo fan and I want this to be a thing. Puppetmaster was a job in Final Fantasy XI and they use fist weapons like the Pugilist and Monk except that they also use astandautomaton alongside them. There are also things that resemble automatons from Final Fantasy XI in the Pugilist's Guild in Ul'dah so there are speculations that Square-Enix initially had Puppetmaster in mind for the Pugilist.
