I was just thinking. In 2010, almost 12 years ago, Blizzard updated Azeroth greatly with new graphics, elements, etc... A lot have happened in the meanwhile, both lore-wise and technically for the game's graphics. If you look at Dragonflight then you see huge improvement compared to what have now in retail Kalimdor/Eastern Kingdoms.
Blizzard is investigating if they should release a Cataclysm Classic. And if you add 1 and 1 together. I would say 'Yes, release Cata Classic' and use the opportunity for Retail WoW to update the old zones once again to match up with the current events in the game. Replace old low res models of objects with new ones, like the trees and treestumps. Most object models in Kalimdor/Eastern Kingdoms are 20+ years old when the expansion after Dragonflight comes out in 2-3 years from now.
And add the Draenei isles and Blood Elven zones properly to their continents (so we can finally fly there). And don't only update the Vanilla zones, update Outlands and Northrend as well. And don't forget the dungeons, BG's and arena's. Those also needs to be freshen up.
Does anyone else agree with me?
