Whats the fastest way to 1-15 ?

Other then Kicks Questing. i'll Dungeon RAF during 15-90 . But problem is 1-15 take least 2-3 hours some how..

 

You can always walk to the instances at level 11 or so. Don't have to be level 15. Also, a select few rare mobs in WoD's nagrand have a fairly high drop rate of the 300% xp pots. I killed around 20 of them and got 3.

 

is the Exp pot sold at AH? , Whats that exp pption name?

 

grind, took like 10 mins to hit level 6 or 7.
and starts quest from level 10. really depends on the zone.

for alliance, the human starting area has higher quests density than orcs in durotar.

but definite grind since you dont want bot to walk miles to just turn in quest while each mob can gives you like 1/20 of the whole bar.....
