Final Fantasy 12 - Zodiac job - healing power [closed]

I wouldn't say that it's worth restarting to get different classes. Items are really powerful in this game because they have no startup time, and the essential recovery items are eventually buyable. (Gil is pretty easy to get, especially once you've finished the license grids and can leave Cat-Ear Hoods equipped on your inactive party members.)

Your Shikari (Hunter) gets all 3 Remedy Lores, so Remedies used by him (Balthier, I assume) can cure practically all status effects, even a few that Esuna doesn't work on. Bushi and Uhlans also get Remedy Lore 1 and 2, which cover everything but Stop, Doom, and Disease (which are not too common). Of course everyone can also use the targeted status recovery items, which are usually sufficient.

Your Shikari also gets 3 Potion Lores, which greatly increases the amount of healing gained from Potions, Hi-Potions, and X-Potions when he uses them. (The Uhlan gets 2 Potion Lores, which also helps, and can get the 3rd from Famfrit, but your Black Mage probably needs the health instead.) Equipping a Phoenix Netsuke also doubles the effect of these items (and Phoenix Downs).

Your Uhlan receives 2 Phoenix Lores, which increases the amount of health people receive when revived by a Phoenix Down. The Shikari can also get 2 Phoenix Lores if you give him Ultima, but your Foebreaker gets Swiftness from Ultima, which is much better.
