Debuffer/White Mage sounds right up my alley. I've never been much of a Final Fantasy person though, aside from the FFT games; played FF3 DS (and that one 12 spinoff), FF1 and 4 GBA, and that was about it. As far as turn-based RPGs go I've been more about Etrian Odyssey, 7th Dragon, Valkyrie Profile, Chrono Cross, Labyrinth of Touhou (Touhou fangame vaguely reminiscent of Etrian Odyssey with an unique and interesting battle system; actually possibly my favorite RPG battle system), and Genius of Sappheiros (another Touhou fangame; I believe this one takes inspiration from Romancing SaGa?).
Final Fantasy XIII is more of a real-time, turn-based RPG similar to FFXII except you get way more input during the gameplay while in FFXII, you plan things beforehand. FFX is like chess with a computer where you get to see the turns which allows yourself to plan things. Well, I wasn't good at RPGs and I preferred more action-y games when I was younger, so I just outright failed to understand basic RPG concept and screwed myself over in Dark Cloud 1, FFX, and Grandia 2. FFXIII became my gateway RPG game and it changed my mindset of enjoying games on their own merit. So, I'd say a lot of what I feel about gaming, how I treat games, and respect games I owe to FFXIII.
Like, watch this:

The issue with its combat is that it's never challenged or pushed to its limits until side quests or in XIII-2's case, the end game which has a difficulty spike if you have no idea what you're doing. This is made worse since Lightning Returns turns the gameplay to be more like open-world, Majora's Mask-esque, instanced combat, Lightning-only and sort of like Kingdom Hearts. The combat had potential, but for whatever reason, it wasn't like in FFX where it kept growing and growing because while you can cheese parts of it, the bosses makes you think more and more. In XIII and XIII-2, it's more of bosses make you think, but not like the side quests that make you feel on edge all the time.
So, for me, it's a good game, but it's not horrible or perfect. There are flaws, but those flaws are golden compared to some other stuff that exists like game-breaking bugs, horrible balancing, horrible performance, and such. It's more of a good concept; bad execution issue.
