Job Suggestions

I will separate the ideas from DoL, tank, healer, dps, and variable.

DoL

Trapper: This would be a gathering class that would go out and set traps to gather monster materials which no gathering job can access currently. They would need to fill a beastiary log using tracking to understand the monsters they're trapping and utilize different traps and baits to gather the materials.

Breeder: This class would benefit from the trapper class and could use live monsters to tame and rear them on a monster ranch, where you'd have to rent out space, the higher the level the more space you can rent out. Able to gather other monster materials unable to be obtained by trapper.

Tank

Samurai: Parry/Counter tank. Utilizes breaker moves to debuff.

Cataphract/Valkryie: Pike + Shield tank. Cataphract using a huge shield and heavy armor; Valkryie utilizing buckler and spear and lighter metal armor.

Martial Artist: Needs a name. Utilizing tonfas to constantly block blows.

Rune Fencer: Utilizing magic to imbue its sword to weaken the enemy and can use abilities to negate magic damage/rid itself of ailments.

Adept: Cloth armor tank that uses orbs to deflect damage, using abilities that can inflict damage back to the enemies as they hit the tank.

Healer

Geomancer: Usings handbells to call luopons to create protection fields and healing fields to support the party.

Chemist: Main hand bombs? Pretty obvious, uses potions and items to buff and debuff and heal.

Dancer: Close combat healer, using fans to gain tp to use as healing.

Necromancer: So this is a different take on it, because SMN basically is Necro. Wielding a scythe and blood magic, this healer uses its own blood or blood of the summoned dead to heal its party. Unique abilities that buff the party.

Druid: Using Wooden Idols to call upon nature to protect and heal its party.

DPS

Cavalier: Utilizing a glaive from upon its mount. Able to fight while mounted, but only battle hardened mounts.

Time Mage: Using rods and time magic, casting magic to debuff and damage foes, and support allies.

Viking: Wielding a great hammer to smash their foes and utilizing their destructive rage.

Sorcerer/Red Mage: Imbuing their rapiers with magic to quickly damage their foes and able to cast support magic to aid their party.

Magic Archer/Mystic: Using an energy bow to shoot non-elemental arrows piercing their foes. Able to debuff the enemy with their skills.

Mercenary: Gunblade wielder.

Variable
*These are classes I feel could fill any role. Since we don't have a support role, having some variable classes would be a neat addition. Their role would be dependent on the form/abilities they have equipped that can't be changed once in a duty.

Blue Mage: Using Dual swords or maces, they learn the abilities by fighting monsters. Change their stance to switch which abilities can be accessed (unable to change once in duty).

Morph: Wields a bracer which allows them to change into the forms of their foes. Each monster is role specific and have abilities reflecting that. Role changes depending on form you're in.

Beastmaster: Wielding whips and able to tame and call forth monsters. Each monster is role specific. Can only stable one of each role.

Puppetmaster: Ordering their automaton to do their bidding. Based on the automatons equipment, will change the abilities they utilize and their role specialization.
