seems it's a temporary change. But hopefully it will give both us the gamers and blizzard a renewed perspective of whether some of the visual and AUDIO themes to modernize D3 was really the right thing to do.
As a big Diablo fan, i'm glad they were creative enough to come up with this. This is what will bring me back to playing Diablo3, having a catacombs and this retro visual nostalgia
Necromancer in 2017 is one of the up coming updates i'm greatly looking forward to :]
