I agree, WoW was never about pushing visuals, it was more about pushing boundaries. Its Art Style is ageless. Playing the game with everything set on Ultra and High makes the game hold up really well. Plus the game has a 4k feature if you have the GPU and TV to achieve it.
The Mechanics have changed drastically, That Blue swing would resemble a special ability eg: Mortal Strike.
I guess that is down to everyones taste. While I do agree that tech wise and MMO should not be pushing any boundarties, the truth is that the game is but ugly for 2016, especially when you are the last remaining AAA P2P MMO. I was never a fan, and I can still play W3 without any issues today, but I think after the last milking (Legion) they should really come up with a new MMO.
