Blizz has graphic art creators?

I would like to know who the visual team designers are, because I just saw the tier sets of the new expansion, and they are more of the same, are the people at Blizz devoid of imagination? It is very unoriginal, it seems that Blizz only knows how to focus on a single point of the expansion, game style talents… it forgets about the design of the tier sets.

It’s a shame to have one more expansion with the same style of tier set design.
