Nah In even now in Classic WoW you can't hit 60 by just questing and doing dungeon/group quests. Even with all the quests that were added with AQ/Naxx/DM ect it's actually impossible you simply have to grind there isn't anyway around it. Blizzard changed it with TBC launch they buffed quest XP and reduced the XP you needed to level at higher levels.Since most quest hubs in WoW also had breadcrumbs to dungeons part of your leveling xp was expected to be dungeons. If you were totally skipping dungeons then yeah, you'd often have to go do multiple hubs all over the place if you didn't want to grind. Even back in Vanilla AoE grinding was the best xp but you didn't get the faction and other side stuff from questing.
It wasn't this way with EQ2 when it launched you could simply just quest all the way to 50 in you desired.
