Paladins and DKs have +20% to Mount Speed but why is it that Druids seem to be able to outfly them to herb/mine Nodes?
They have a talent in the first tier that is +15% movement speed. I dont know if it works in flight form though
druids dont need to dismount for gathering herbs and as a tauren druid you have faster gathering of herbs...
Druid flightform is pretty damn good for herbing in high concentration areas although DK/Pally's are still very good and worth considering for their survivability alone.
It can be a number of reasons: -Talents -Druids don't dismount -Guildperks or a combination of those.
