Honestly the most logical choice is chemist imo. When you look back on all the FF titles and the lore. Chemist would fit perfectly as a healer. Now that being said there isn't any reason why it couldn't be a DPS also.

This just makes me want support roles more and more. Understanding the boss you are fighting knowing the elements associated with each encounter. Having a log of "scanned" enemies and using there weaknesses against them. What debuffs they are susceptible to and using that against them. Sounds kind of fun imo.

Geomancer and Chemist just get lobbed into support roles and party size for dungeons goes up to 5. 8 Man becomes 10 man, so on and so forth. Just increase the HP values and adjust the damage from the mob.

I think it's time we got a dedicated support role job that has a lot to do with elements and buffing the party, and debuffing the boss. Astro is kind of like this, only think of the support role as just KEEPING those buffs up to "DPS". Instead of just straight out DPS from a weapon, they enhance all DPS.

There is quite a lot of emphasis on DPS from all classes, but not emphasis on one class devoted to holding a buff up and giving en-fire, en-thunder, to enhance DPS to counter an element. Or Shock Spikes, Blaze Spikes thorns. Status effects like blind, slow, stop or dare I say Fury. Fury the boss takes more damage but also hit's harder.

I don't know I think it would be fun to just play a strait debuffing/buffing class. I used to get that from astro, but not it's just damage increase. Miss my spread and royal road.
