If you haven’t heard, tier sets are going away in Battle for Azeroth. So Antorus (Tier 21) will be the very last tier where we get class set bonuses. It’s also the final tier of the expansion, so that must mean Blizzard is going to give the system a nice send off and give us some truly cool bonuses to enjoy while we wait for BfA, right?
Oh, sweet summer child. No.
Updated Dec 4, 2017: Small buff to T21 4p. Set bonus section updated. Not much has changed since this is an inconsequential buff in the grand scheme of things.
Updated Dec 5,2017: Updated trinkets section because of hotfix buffs to them. Antorus trinkets are more useful now.
