I disagree. I think there are myriad ways it could be implemented as both unique and functional as I said above.
Technically there are 4 FFT games. My point? mix is not the best known move of the chemist/apothecary. Also if you include less cannon ff games FFBE has many chemist job characters. side note but you could say XVs magic was more similar to chemistry.
As I suggested above i don't know that it would be. Consumables can exist in the form of charges. And i think having a healer that doesn't use MP but instead operates on a differently managed resource would be very interesting. And is the depth of development any new class should get anyways. I didn't say this at first cause I figured you might be able to connect the things i mentioned in my first post (charges and insta casts{which was why they occured to me}) with this part of your argument.
Using the fact that there hasn't been enough well thought out fan designs as an argument against the classes creation... doesn't really work. Just because no one has had the time to flesh it out doesn't mean it couldn't be done. in fact this thread is inspiring me to do so.
Why would it be overpowered? or wildly imbalanced?
if implemented as I loosely suggested it would be more bursty sure but i mean WHM has Bene so..... But the whole thing is it would be more skill based. Nothing would be truly instant if every good heal had to be ground targeted. It would be skill based and there would still be some delay after dmg before a heal can go out, or learning of the fight to begin the cast pre-emptively.
Thats just plain false. Like said it would be realllllllly easy to just convert a few of the role abilities to fit with a trait as i suggested. and Mind/piety as a main stat group still makes complete sense for a chemist, especially when dealing with enchanted potions and things such as holy water.
ALSO silence is a non issue. Silence also turns off a bunch of melee class abilities. Silence in this game isn't really silence any more, its just a form of disabled. You could easily reason around this by having the apothecary need to trigger the effects of potions with a word or something. the point being: silence is a non issue.
Frankly your lack of confidence in the devs ability to create unique and functional content is insulting to me so...
The above is a very fair analysis.
I agree btw completely with your analysis of geomancer. but i think there are a lot of flaws in your reasoning behind why chemist wouldn't work as a healer. And I also think bottle throwing as a dps mechanic would end up dumbed down to be either: A rather lame, or B stupid complex.
