Laziest Designers Ever?

What is wrong with the designers at Blizzard? Are they officially the laziest designers ever? Why can't they make new Armor Sets? They've re-used Tier 1 & 2 already and now they're re-using T3 as well for both T7 & T7,5. Yes its from the same dungeon but still. They could make an effort you'd think considering all the money they make.

I'll admit that the Tier 8 sets do look rather new. But they all look pretty much the same... there's no... sense of awe about them. Did they fire the guys who made the first two sets? Back in the day of Tier 1 & 2 when Epics were rare... people were in awe of the sets. They looked so nice and shiny!
