I may likely be a minority here when I say I want camp/party based grinding. The real prize is endgame, that doesn't mean the climb to 50 has to be boring. If the enemies are interesting, and the battle system is fun, I'm personally content with a party based enemy grind system to level up.

Considering the large unused areas on the map, certain locations can be populated with aggressive or friendly enemies that can be used to XP from.
