Patch notes are awesome. With all the new cold skill/supports I'm going to try a dual cold claw EV/AR/Fort Ranger with Rage, Smoke and Whirl, and a Golem on the side. The change to Ondar's is going to take some adjusting (I always used it on my melee EV chars to eliminate the threat of ranged, non-caster enemies; but I cannot deny that it was OP), but I'm sure I'll be able to compensate.
I just don't know if I want to try Tempest or Warbands first.
