I like the idea of an SP reward for exploration. I really enjoyed discovering new areas in WoW. I liked the on-screen text cue that told you the name of the new area you had entered as well as the sound effect that came with it. It added to the sense that you were striking out into new and distant territory. The exp reward was like the cherry on top.

It's a minor feature, but it's nice. I'd like it if they added it to FFXIV.
