Shadow grade NB here, one of the few I see that uses up close hidden works. Lately I find in my Cadwell silver travels Mobs breaking my Invisibility. It usually is bosses, and maybe groups of 2 or 3. Correct me if wrong but I dont think that is supposed to happen. This is potion or Shadow Cloak Invisibility. I also dont think its meant to happen, because I can be up under other mobs noses and NOT get detected within the 3 seconds.
Also of late in Cyrodil I have seen a distinct type of DK and/or Sorcerers hide from 20 or so searchers for long period of time. Usually starts with poof I am gone which I believe is potion because they dont crouch, then even though mage lights are nearby and things are wide open in the plains, no one sees them for awhile until they peel off a fish and attack them.
My stealth/invis skills are not that leet. I smell an exploit.
