Last week, data mining began on the patch 9.2 Eternity's End PTR which all upcoming class tier sets which were announced to make a return were found including all 36 2 and 4 set bonuses that were then revealed.
Nothing is final as this is a PTR and there are both some very strong and very weak set bonuses so expect some nerfs, buffs, and potentially reworks for some of the specs.
This is also early data mining from Wowhead, with the PTR not currently live, and is not expected to go live for at least another week before players get to test these Tier Sets out for the first time.
