So you used attacks, limit breaks and Draw/cast against the enemies?
Never used any magic. It's literally only attacks and healing items and limit breaks of course. As soon as I can access new magic to draw I'll max it out and bind it. Limit breaks with maxed stats are already way too powerful. All that GFs would do is drag out the fight.
The key to the game is GF leveling, controlling how they level. Early game bosses is using them to do the fighting for you as they are more powerful than you, late game is you doing it instead after leveling them up correctly. The Junction system is actually more in depth then people think.
Most important is Refine abilities, they allow you to compensate for lack of draw to max out characters traits.
After about a few hours, I don't even use items at all, my main thing is Attack, Magic, Draw, GF with a couple of other things later. Magic was only for heals or elemental bosses. Final bosses are 'Meltdown', to burn them, then Aura on Squall who has ultimate on Attack. Win.
If PS5 BC is a thing, I'll considering getting this as long as it's not too expensive. I mean I can play FF8 whenever but would be nice if I could just turn on an play at sometime.
