Well I can see why spawning enemies rarely is a pain. Imo for FFXV it's no big deal, cuz instead of lvling up and being op you can use a magitek armor idr what's it's full name, but cid gives u it and your basically invincible when u wear even in bosses, except for phase 2 against Ardyn when u fly. But the Armor has battery charge, but I can recharge back easily if u don't use it. And if I'm correct it can charge off game time, meaning it can still charge after u left the game.
Although it might be a pain to grind in FFXII but I doubt there's anything that lures enimies to u like how the whistle in XV that apparently doesn't work.
Idk I chose the agility because it's so annoying when I can't hit the enemy in the game, like they hit me instead and I got to use a potion or Phoenix down or anything else to heal me plus getting gil is hardcore in this game. The best way is just to sell items or equipments.
