I think stealth should be used two ways:

1. 'Softens' your footsteps when you're walking (the sounds they make), so players wouldn't be able to hear you moving about as easily if they had sounds on.
2. Make monsters have a lower chance of noticing you, either moving around or stealing.

Maybe have it so items have a stealth rating, RoT's having a stealth+5/10 rating, so dual RoT's would be more efficient in this than one.

Hiding should just flat out be a skill where if you don't move or switch skills, you can be invisible.. maybe make it so if a player or monster is in close proximity of you, you'd turn slightly transparent instead of fully invisible to everyone else. Perhaps make the time available for hiding scale with agility level. (i.e. A person with 1 agility could only hide for a few seconds, a person with 107 agility could hide for many minutes)
