In the Wolfhunter Patch, ZoS made this change:
Decreased the range of Two Handed, Dual Wield, One Hand and Shield, Unarmed, and Werewolf Heavy Attacks to 7 meters from 10 meters.
Did they really have to reduce the range of Unarmed heavy attacks?! This makes my Khajiit Hand-To-Hand Expert Ninja Nightblade Healer Assassin basically useless now outside of elite role playing circles.
On a positive note, this is a much needed nerf to Vorenor Winterbourne, the final boss from Spindleclutch 2. He was much too strong before.
