关于4E 游侠的范围武器攻击

[无名亡者]

Sweeping Whirlwind   Ranger Attack 7
You slash and stab at surrounding foes with unbound fury, knocking them off balance with thrusts and leg sweeps.
Encounter ✦ Martial,Weapon
Standard Action Close burst 1
Requirement: You must be wielding two melee weapons.
Target: Each enemy in burst
Attack: Strength vs. AC
Hit: 1[W] + Strength modifier damage, and you push the target a number of squares equal to your Wisdom modifier and it is knocked prone.

对这类需持用双武器的范围攻击，在骰攻击和伤害时用主手还是副手武器？或者是可以随意混合使用两者？

個人理解 RAW 是隨意選擇一個用在所有攻擊上, 不過 HR 成任意混合也很合理.
