Wishful thinking; but I hope 2h Enh in SoD was some attempt at testing how to get 2h Enh working in Retail. 2h Enh isn't a role change like shaman tanking, rogue tanking, mage healing, etc. The only real hurdle beyond tuning would be getting Stormstrike and Lava Lash to work for a 2h weapon.
It would be another W for Blizz imo. Plus with Thrall taking a leading role again, being a shaman with a 2h axe; it would make sense to let players replicate that fantasy.
