Even if stealth as it applies to combat were to have limited usefulness it's still an immensely useful skill in this game.
Being able to dictate when or whether there will be a fight or not by evading your enemy or waiting for the right time to jump him is of obvious value.
Let's not forget that this is a game for control of territory. Having the ability to covertly recon an enemy encampment would alone be enough reason for a number of characters to train it.
So they make good scouts. Which usually work alone. But they can't kill a moss snake solo so if caught by even one enemy sentry the rogue dies or has to run.
The only benefit to having a stealther scout is so the enemy doesn't know they are being scouted. But anyone on sentry duty will have just as many points in perception. Even if they don't the attacking party should assume that they will.
So knowing your scout will probably be spotted attackers will have to come up with a plan that doesn't involve stealth. Just to be safe.
So while your raid leader will humor your scout because he feels bad for him, his actual plan of attack won't rely on stealth at all.
