and i wouldnt tame your windserpent bite, i would keep it at *Avoidance dive, growl and LB. (use the remaining points for Stamina/armor for PvE or *cobra reflexes and frost/shadow resistance for PvP)
Bite is about 50 damage or something. if its higher, i know it doesnt get over 100. its 35 energy and a 10 second cooldown. Lightning is no cooldown, 50 energy and is about 200.
