The Final Fantasy series is filled to the brim with amazing and diverse classes. We all have our favorites but these are a couple I wouldn't mind seeing in this game and I wanna see what everyone thinks about these classes and offer ways on how they could work.
Mediator- Utilizes linguistics to aid allies and enfeebled enemies. Basically this is a class that uses speeches as spells. We currently have bards and dancers, we got the singing and the dancing, how bout the speaking? The way it could work is you use scrolls as weapons, and your rotation could be chaining speeches together to make powerful statements.
Calculator- Wields the numerics of war. Someone who uses math to fight. As lame as math can be I think Calculator could be a powerhouse of a class. It can use an abacus as a weapon and the rotation can vary depending on percentage of HP, MP, and TP of allies and enemies.
Evoker- Glorified Summoners. You may be thinking well we already have summomer what more could evoker do? Well it can open up an opportunity to utilize summons for more diverse class options. Bismark for Tank, Unicorn for Healing, Tonberry for DPS, with the evoker class you can have summons that take on roles of main classes.
Lanista- Soul Sappers. Again essentially glorified Dark Knights but I feel that Lanistas can be heavy users in Drain spells. Osmosis, STR Sap, DEX Draw, and the classic HP Drain Etc. Lanistas can operate as extremely ferocious healers. Drain enemies of needed stats for your party members
Chocobo Knight- We have chocobo companions we can fight with. Why not take it a step further? Become a full fledge chocobo militant. Tame Yellow, Black, White, Red, and rare chocobo breeds to take on mainline roles. Combination of a Warrior/Summoner but very Chocobo focused.
