Ive been having great success with ice lance on druid. It can roll on mastercrafted gloves, boots and belts so its easy to get ice lance lv100+ and druid has many other skills that boost the build. Easy 200 cold pen, free +phys and +cold dmg. Use hellreach bow + kingsport for most dps. I have points in 6 skill trees.
Stuck right now @ sam and getting T10 riftstones. I call it skill issues and lack of final optimizations. DPS is there for anything its mainly surviving in higher rifts, can make some swaps to make it better I guess but few big gains there mostly familiarity with rifts.
After this season the extra needed max res might lower dps though, but there is place for it in sockets and fire res is free anyways with bow and kingsport.

Wyrd oskill is quick and fun to farm with, only tried up to dunc so far with melee wyrd necro. I bet its fine up until scosglen, then it might become too slow. Needs bitter harvest, maybe not ssf
