You do realize there are various Save Crystals throughout all the areas in this game right? :/
So the hunt was really, super tricky. Not everything is always fair after all. Sometimes you have to work for stuff. Are you saying you don't want a challenge and just want to breeze through a game?
And you don't *have* to spend a ton of time training in this game if you don't want to. For example, I've spent tons of hours leveling and training to accomplish expecially the hunts, but that's how I do it with every FF game. FF12 is no different trust me, and I've played every FF game and been an RPG player for as long as you have. Conversely, my fiance finished the game very quickly and was able to also complete most of the hunts with significant less training time and lower levels than me. Once again, that's his common method with every RPG he plays, including all the other FFs he's done.
And ya the hunts can be hard, but they're not compulsory. In general sidequests in RPGs often are harder than the main storyline. At least in my experience. For all I've said concerning leveling up, when it came to hunts, I also knew I needed to use patience and strategy to win.
