Changing Zhevra Mount for Flying rocket.

A month or two ago i recruited my friend. This lead to me eventually getting my Zhevra 100% land mount. This made me content and i was one of the first on my server to show this bad-boy off. However only a month after recruiting him blizzard offers for the same amount of effort, a 280% flying mount than can hold my friend aswell as me. This in my opinion is hugely unfair and really makes me frustrated as non of my other friends want to play WoW so i can not possibly get the flying one. My friend just hit 60 and is progressing through outlands. Sadly to help him i have to ride on a ground mount instead of just loading him into a nice new flying rocket and zoom him around like a real friend should. I would greatly appreciate it if this could get sorted out so i could help my friend faster and get what i deserve from recruiting a friend.
