Levelling my WWsin was very easy at low levels. This is my usual strategy:
Levels 1-5: Clear Blood Moor in a full game. (1 game)
Levels 5-7: Do Den of Evil/Blood Raven/Save Cain solo.
Levels 8-14: Clear Black Marsh/Tamoe Highlands in full games. (2-3 games)
Levels 15-20: Sewer Runs in full games. (~.75 games per level)
Levels 20-24: Norm Cow runs.
Yeah, getting a character to level you in cows is kinda rough (if you don't have any friends on).
The gear my Asn wore:
Helm: Sigon's
Weapons: Gemmed Katars
Armor: Greyform
Gloves: Death's
Belt: Death's
Boots: Sigon's
Rings: Whatever (Rare life leechers and manald at appropriate levels)
Ammy: Whatever (Eye of Etlitch at lvl 15+)
