Overall player stealth was nerfed as it was OP.
buff - "Stealth is less affected by player movement and ramps up over time"
nerf - "Balanced stealth effectiveness for all combinations of perks, armor and light levels"
nerf - "Reduced distance from and radius that AI picks to investigate near the target"
nerf - "Balanced stealth world and block ambient light"
nerf - "Balanced player stealth enemy search duration reduction from perks and armor"
buff - "Increased Assassin and Rogue outfit sneak effectiveness based on other stealth calculations and balancing adjustments"
nerf - "Increased bear and dire wolf sight and hearing"
