I already do that with Deviljho, but I wouldn't count them as "small fry"(post I was replying to).
Still, the question remains, what would stealth add to MH? Do you just hide for 50mins in a Deviljho quest? Obviously, I assume time limit will be removed in MH World, but it still feels out of place in a game like MH, to me anyway.
In a typical stealth game, the point of stealth isn't simply to hide, but to give the players a massive sense of accomplishment once they reached their goal through stealth, whether a destination or a kill. However, I just can't see how we could sneak-attack-one-hit-kill a Fatalis or something...
