Next time this game tells me the recommended level for a dungeon is level 50, I'm going to listen to it. Just did the Mines at level 39/40 with no status boosting meal, and now I have no Phoenix Down's, Potions or Elixirs. Bright side is, I did manage to kill the Boss, and collect the Royal Arm.
I will say that between the Regalia and hireable Chocobos, traveling from quest-to-quest, and hunt-to-hunt is no longer much of an issue...and since it's only 50 gil per day to hire a Chocobo, I'd say the cost is reasonable. That said, I've essentially dropped anchor as far as the main quest is concerned....I mean if I paid for 7 days of ride able Chocobo's I am going to GET my money's worth.
