Don't get me wrong, Hexing pants is still a very good cube candidate since it's 25% dibs. It just won't solve your rage problem. Honestly, Hexing or Leorics are probably the only two worth considering. Or maybe something from the bracer slot in case you want to wear a Lacunis to hit a breakpoint.
Sure, it's just much less powerful. Non-season pre 2.3 didn't have access to Orotz and WW was still tops. But there's zero reason to not use it now. You need the ring, Boon passive, and about 30% CDR to get full uptime on WoTB plus some other CD usage.
Please, don't cube an immunity neck.
