This is horrible balance and is in part what has led us to where we are now in terms of pvp balance issues. You shouldn't need sets to counter other sets, and sets shouldn't be used to solve balance issues within the game. That is how we've gotten plaguebreak, Rush of Agony, convergence, maras, snake in the Stars, etc.…
It will mean, for most, some more mixing and matching and changing gear. I would wait to see which sets are broken or, rather, which sets aren't broken as the track record on this is shocking. I expect most of them to not work properly.
Dear ZOS, Valkyn Skoria has been broken for years now. A lot of times, the meteor circle shows up on people’s feet but then it never drops to hit people from the sky. On random occasions, this set will work, but does not work 95% of the time. Please fix this as soon as possible. @ZOS_Kevin @ZOS_GinaBruno
