I know I'm not alone in noticing that ever since knucklebones were added, the success rate of obtaining a WW from the campaign has been noticably lower.
I really do not like when a site states they change things like encounter or success rates, but give the players literally no information on what was actually changed.
I know that the encounter rate was reverted to normal, but it really feels like the success rate was stealth nerfed and no one told us.
