So in Oblivion, the higher level sneak you are, the greater you were at sneaking around (in general). In Skyrim, it seems that there is a specific perk that makes you harder to detect... does anybody know if this is the only way to make yourself harder to detect with skill, or is the actual skill level *also* affecting your ability to sneak? Seems like the skill levels now simply unlock perks, and don't have bearing on actual effectiveness?
