I want to say that I am really grateful that Blizzard will implement new skins in patch 5.1, which would include the grey dragonhawk and the black dragonHawk. I think this is a step in the right direction because the implementation would not just gives an opportunity for hunters to gain access to certain family skills that currently requires the hunter to go into a specific zone, but it also will help other toons to level up by giving them extra green gears and xp.
Having said, I think a lot of hunters had expressed their disappointment of the omission of the armoured dragonhawk skin, which was previously intended for Sunwing. I really love the black dragonhawk skin, and I think a lot of hunter feels the same way too. Thus, in my humble opinion, that the armored dragonhawk should be made available via a normal mob instead of a rare mob. I think there are a few Outland Dragonhawks that shares the same colouration with each other and Blizz should use at least one of the non rare mob in Outland to use the armored skin. Here's a novel idea, the Crystalsong Forest would make a great place to place a small flock of feral Armored Dragonhawk

I don't mind the grey and black dragonhawk skin to stay elusive and rare as in the spirit of MOP, most of the rares are only different coloured skins of the normal mobs anyway. As for the ghostly blue gemmed owl, why not make it one of the colours available for the ghostly gemmed owl in Stonetalon?
I do hope I make some sort of sense here lol

Horizons of hawkdragons, armor of red ire, someday
