When you guys played Golden Sun, did you mix and match Djinn to change classes? I actually like the idea of a custom class system, but having to put different elemental Djinns onto the Adepts was too uncomfortable to me I'm starting to wonder if maybe I'm a bit OCD. I'm replaying GS now and I see I've missed out on a pretty big game mechanic.
In the end, I prefered the original classes. But there where some cool ones in the bunch. In the early game, switching Venus and Mars Djinn for Isaac and Garet is quite beneficial. Garet becomes stronger and faster, and the Psynergy is just very strong early on. Soon as Isaac learns Ragnarok, I want him to have the Venus Djinn yet again. Barbarian classes are cool for Garet, but not so much for Isaac. Specific fights for specific set ups also work. I liked the Jupiter / Venus Djinn classes for Isaac as well for example, Thunder Mine looked great.
Ivan can only really benefit from Mars Djinn though. I really dislike anything else but Mars and Jupiter on Ivan. He's too frail to be the main healer, and if everyone remains original, having Isaac and Mia heal when it's needed is more than enough. Also, my strategies often have Ivan spam High Impact for the Attack boosts.
I also rarely used Djinn to attack, only if I needed Summons for boss fights. Buff Isaac's attack up, let him spam his weapon or Ragnarok / Oddysey, and let the others either heal or Djinn spam or Summon. That's my general strategy if I was fighting a tough boss.
Would your ideal GoldenSun HD collection be full 3D remake, handdrawn sprites, or Octopath style?
I think I'd lean Octopath personally.
I think some sort of mix between the cel shaded style of Breath of the Wild and Octopath would fit well. The scenery, Psynergy and Summons need to be breath taking.
