(lvl 32 human rogue)
I have noticed that mobs see you pretty far out of stealth sometimes, but It hasn't been game breaking for me at least.
HOWEVER, when i'm spotted in stealth, it SHOULD NOT be removing me from stealth. (Pretty sure this is not supposed to happen)
For example, if im trying to get behind a mob, and garrote, pickpocket, or ambush them, and they see me, i used to spam cheap shot when they turned and stun them instead as my opener.
Now i just get taken out of stealth entirely, which I think is not Working as Intended
