It's a flawed combat system (but I still love it). If you really want to grind, you should go fight Cactaurs on the island in the south. They pretty much die in one hit and give crazy GF XP. You can then unlock all of their abilities and refine cards/items into some of the most powerful magic to junction. You can also get parts to upgrade to the best weapons.
Honestly I don't pay for a subscription for the premium content, I pay because I love Giant Bomb and want them to be as successful as possible. If they didn't even have premium content I would subscribe for the sake of subscribing.
@egg: I'm not taking a retrospective. Just sitting down for an afternoon and playing some current generation games before they are retired. They don't really have much video for any pre-2008 current gen games.
