I also see that you are using bracers and weapon in cube that focuses primary skills. Whirlwind is not primary skill
In cube use: Skullgrasp / Hexing Pants of Mr. Yan / Furnace
Switch bracers you use for Nemesis (my prefered), or Lacuni. If you want to stick to cold damage for WW and tune you are using, great choice would be Strongarm bracers ('cause you are pulling them, thus activating Strongarm passive). But I'd suggest healing rune for WW.
And take into consideration swapping Pain Enhancer for Gogok (in which case I'd go for Veterans warning rune on Warcry, to further boost dodge chance).
You need Taeguk for WW build, drop Efficacious.
