What does sneaking do besides not making you fall off cliffs

Make you walk slower. :D

I think it should make you invisible or at least hide you a little.

That would be uber-cool. And it would increase popularity of pvp servers, then you would be able to shout "Suprise! It's buttf*cking time", when you get close enough to attack.

i think that having armor is a need also but if you make mese armor then you become entirely invisible. having an animation would be nice.
