Many months ago Yoshi said that it was not his intention to introduce Sneak/Invisible spells in the game. But all ex-FFXI gamers know how "fun" could be just explore the land with those spells casted upon us. I think that should always be in the game places with extremely though enemies (not speaking of Goblin Liv. 99 like in this version :P). It would make the game and exploration more thrilling!
