You could get to Furbolg "unfriendly" rep pretty easy, which would make them at least not attack you. This way you could get to both Moonglade and Winterspring. Also, the druids (Cenarion Circle) were neutral at the start (Brood of Nozdormu wasn't, that was tied to the AQ opening/raids), but you couldn't use the flight master in the druid camp as a non-druid - which would only fly you do Darnassus/Mulgore anyway. Non-Druids had to use the flight master at the south shore of the lake.
The only reason to go there for non-druids were the enchanting recipes (which were BoP), and some quests regarding Maraudon (Seed of Life) and Dire Maul (Shards of the Felvine, which started in Moonglade). Lorelae Wintersong had the recipe for the "runed arcanite rod", which was a thing for enchanters back in the day.
She also had the recipe for the felcloth pants, which were +26 shadow damage. Itemization was much more creative with stuff like this.
