It does not, because not taking SB is a large buff to DW. 2H cannot hope to close to gap now, and we can see why when we look at the advantages for DW.
- Attacks faster, netting more natural Killing Machine procs and Icy Death Torrent procs
- More free Glacial Advances from getting more Killing Machines
- Free 6% Strength from getting the benefit of a third Runeforge in Stoneskin Gargoyle
The best case for 2H is still AoE, where it can fully capitalize on the +30% Obliteration damage. But even there, it still lags DW.
