I picked Shadow Disciplines for the extra Movement/Attack Speed. Makes you virtually impervious to slow effects while moving like no other Amazon before you. I get having Amplify would be so nice but there are ways of proc’ing it(albeit at poor rates unless you roll with Wrath/Brand or Reaper Toll Merc).
Edit: Here’s another one that would be stupidly broken as F#!#$
Tree#1: Offensive Auras(Paladin)
Tree#2: Defensive Auras(Paladin)
Tree#3: Fire OR Lightning Tree(Sorceress)
