A few days ago, Bornakk responded to yet another thread regarding dual wielding for Death Knights. I read it, shrugged, moved on with life, but I found myself digging up the thread again because I started to warm up to the idea Bornakk put forth: They're considering (that's the key word here) "something like making the frost tree the dual-wield tree" and letting the strikes hit with both weapons like Mutilate and Stormstrike.
Bornakk says balancing both Dual Wielding and 2Handers in each talent tree has been exceptionally challenging, and I think we've seen that firsthand. Talents aimed for one build make their way into another, and things quickly get out of hand. Turning one of the trees specifically into the Dual Wielding tree (whether it be Frost or Unholy or whatever) is something I can get behind, even if it runs counter to what they've been trying to do with the talent trees since the Wrath beta.
