the muffle effect is cool, and the bonus to lockpicking fits, but that's it. you might want the bonus to illusion, but the boots already have a permanent muffle effect, and do i even have to mention the shadowcloak of nocturnal. overall the set feels like it's more geared towards warrior type of players rather than sneaky thieves, with its bonuses to stamina and one-handed.
sure, it shouldn't be just an upgrade over the thieves guild armor or the guild master's armor with better stats, but at least it should represent the skills that fall under (or close) the stealth tree. where's pickpocket, alchemy, speech and better prices, or maybe archery? now, i would imagine people wear it mostly for the looks.
