I like how zos' answer to balance problems and overtuned mechanics is to create sets to specifically counter those mechanics. They can be hit or miss but its really a lazy way to go about balance.

Other examples are plague for purge spamming, nibenay for pulls, snake in the stars for cross heal spam, sentry for stealth, shield breaker for shield stacking. Like I said these can be hit or miss on effectiveness.

Safe to say, if they make a set to counter a specific mechanic, they have no intention on actually balancing or fixing said mechanic cause they can just say use x set if you don't like it. Out of luck if the set sucks and it also really hinders your build if you specifically build to counter a broken mechanic. Even if you decide to wear these sets you're still limited to a few options, so you have to pick and choose what mechanics you hate fighting against the most. Kind of an absurd answer to balance issues if you ask me. Still it's kind of funny that by making these sets they're in a way admitting something's overtuned.
