totally agree with Ughmahedhurtz

For druid/shaman, I don't think it is any significant benefit in buying mount at 30, having travel form/ghost wolf is way faster to move around as they are instant cast. Casting mount up wasting a couple of seconds. For me travel form/ghost wolf move my fleet - see mob cast spell killed - change form run again... go faster than mount up and down.

for the leveling side; i don't think in Darkshore Ashenvale is the best area......run around for miles to do a quest. It might not be true if you manage to find the circuit with you can do all quests in a round. I think there is such circuit but don't remember where i saw it
