Old World Level Scaling

is there anychance anyone from blizzard would mind doing an Open world scaling for max level players. it would keep players that enjoy wow atleast a majority ive always wanted to go back but making a new toon for each expac or area beacause of how quick the leveling is currently. All i want to be able to do is take my max level 80 paladin around the world and do the major zone quests and fun side quests everyones forgotten about.

It better be optional. Because the actual majority of players would hate it if it weren’t.
