One of the biggest complaints about the otherwise fantastic Ward of Elements x2 raid zone is that by upgrading a few pieces of armor to T3, fighters and mages lost huge 5-piece bonuses from their T2 armor.
An undocumented fix in GU52 is that these bonuses are now distributed over the set bonuses in such a way that 3 pieces of T2 and 3 pieces of T3 will yield a similar bonus to having 5 pieces of T2.
This is fantastic news, as it seemed this would be a long-term fix based on the Zam devchat. Glad they could squeeze this fix in sooner rather than later!
Although it’s not really posted in the right forum, I’m going to link to the thread which has the first information about this fix that I’ve seen.
