9 min read 0 0

When showing off what new additions await us in patch 9.2 Blizzard showed something we’ve been waiting for for a long time – the return of tier piece Sets. All of the piece Sets have the same visual aesthetics of “class progenitors”, but more importantly the piece Set bonuses are also making a return.
