(Edit: Increasing obvious that people wouldn't be behind this as RDM. So, I'm going to go with Machinist)
New Class 2: The Chemist (healer)
Yup the chemist from Tactics. I saw a post about this on a different gaming outlet and thought idea would be cool. Basically the chemist focused on single target cures, buffs, and debuffs. The chemist can cure any status, can heal mp, and can cast the "potion of X (de)buff" on a player or target. For authenticity sake, the chemist is required to have the potion they want to use to cast for a skill (skills require the potion). There can, however, be new potions types such as "panacea" and maybe more that serve the function of being a dummy potion that can be used by the skill.
However, the additional effect of casting a skill with the real potion can be a more potent effect (giving players and incentive to use the real thing). Phoenix downs would need to be put in the game and are chemist usable only. Would let chemist rez the fastest in the game (but the rez won't restore much hp). Chemist use guns (rifle) which supplement their "throwing" of potions at teammates/enemies. They will be a ranged support (healer).
New Job 2 Machinist (CHM/don't know what other would go with it): Functions similarly to the chemist but gains the ability to cast supportive potions on the entire party at a reduced affect as well as the same for debuffs (at some point... or in typical FFXIV fashion, just gets the +II version). Gains an ability to dose their gun with potion to fire debuffing rounds (magical rounds).
Stat focus for both: Dex/Int or Piety. All skills for the CHM/MCH cost mp. Int will increase magical bullet dmg (unless it was collectively agreed that no one would want a gun to fire magical dmg-in which case, INT wouldn't be necessary). Dex is for the normal bullet ACC and dmg similar to ARH. Not sure if they will wear caster armor or and medium DoW armor. Probably whatever the BRD wears.
I think CHM/MCH would fit nicely in the dmg. This healer role isn't about DoTs or the occasional AoE nuke. They can be more supportive in the buffs they use, and due to the speedy nature of their "throw" abilities and no requirement to enter a stance, they can put out steady dmg and debuff. I haven't played all of the class/jobs yet, but I feel there is room for a class of this nature.
What do you guys think?
