Classic About the graphics update and the retail/classic split

At its core is retail still the same game just with access to every expansion. Or did they not bother moving over some quests models dungeons etc when they did the glam up a few years ago. Like all the quests that didn’t really go anywhere. Would they have bothered to touch up them for zones even on busy servers ppl never went to?Just kinda curious what’s there and not and what I might jump back into. via /r/wow https://ift.tt/kbefodi
