Lol players would go crazy over Dracthyr being able to Meta! DH already have Godzilla Breath just need the Laser beam of Havoc! This and Druid Dracthyr would probably be one of the most popular because all their transformation would look like different types of Dragons… Hmmm DK could be popular too if they actually give a Skeletal Frost Wyrm CC option among other types of skin VFX for undeath.
And we even kinda saw what this Meta would look like in Aberrus Raid with Scalecommander Sarkareth! He did it first as an Evoker sure, but it was the first Void Meta we seen even before DH:
Although I think if anything it be an Evoker Hero Spec maybe, but the Assets could be use if Blizz ever decides to allow Dracthyr as DH.
