I really don’t see how the Frost (or Unholy for that matter) tier sets accomplish this stated design goal. They’re neither interactive nor complex and don’t really add anything to gameplay aside from whatever talent changes the robot will tell us.
Another major negative aspect of this set is making 2H builds less viable, especially when combined with the nerfs to Obliterate/Frostscythe. This is a huge nonstarter and the latest annoyance that stems from the fact that Blizzard devs refuse to properly design the spec.
As always, the main problems are the lack of parity between runeforges and auto-attacks. These are easily solvable problems that make the spec un-fun for big chunk of Frost DKs regardless of which weapon type is ahead.
I don’t know if this is a CS or dev problem, but I’ve never seen such an easily fixable problem with this much feedback that’s gone completely ignored for this long.
