It was the same with The Caverns Below. It was initially derided as another "junk" quest, until Dog made the first iteration of Quest Rogue at Ungoro's release. Even then it was kinda iffy, and it took a little more time for people to realise that Elementals, Bilefins and Vanish worked much, much better than Moroes, Violet Teachers and VC.
No-one expected Quest Rogue, right up until the current version came out some weeks after the expac launched.
