Remember one thing, the achievement intially was to kill the bosses before the NERFS, then Blizzard decided to try the item upgrade route as "nerfs" and se what happens, but initially the nerfs were going to be delivered BEFORE the next tier.
Blizzard made a decision to not nerf T14 in the middle of it, and we are saying here that it was a mistake. And IMO, the mistake was to make the tiers so overtuned in the first place.
