Short Ninja Review & Aesir included, Ninja had a lot of powerful Auto-Atk rune to support,
Example (Only highlight useful one):
Deep Mist Hiding - New Hiding skill, attacking won't cancel hiding stat.
Shadow Leap had 30% Chance Auto-Deep Mist Hiding after leap
Mirror Image - Created clone receive 50% lesser dmg
Blaze Shield - 20% Auto-Cast if attacked by Melee
Makibishi - 100% AOE Stun+Bleed, AOE last 10sec, Max 2 per times.
Samurai Soul - While using Sword, P/M.Dmg receive -6%
Auto-Atk Combo 1 - Auto-Atk reduce the target's movement speed by 30% last 3sec
Auto-Atk Combo 2 - 4th Combo dmg+40%
Auto-Atk Combo 3 - Every 10Agi increase 2% Auto-Atk Dmg. (Cancer)
Double Fuuma: Throw Fuuma Shuriken had 40% Auto-Cast Throw Shuriken
Fuuma Shuriken Dmg+30%

忍者的普攻流派看起來收益最大, 尤其是沒10敏捷, 普攻傷害+2%這個就很惡心了.
普攻攻擊時, 對方移動速度-30%也...惡心?
