Dungeons are now more Esport that’s why they are like this.
Zones in shadowlands are not pretty at least for me i don’t like them cause doesn’t feel like wow to me
But it’s terrible to compare them to old zones cause shadowlads look like this becuase of LORE reasons
even ORIBOS is like that becuase of LORE
it’s not like blizzard thought that ooo dude we just put object that look like battery in the middle of nowhere 
BFA zones and main hub for horde was waaaaaaaaaaaaay better than whole Ironforge cause it was actually city of ZANDALARI trolls
