Vrykul should be Playable

I was disappointed that there were no new playable races in Wrath of the Lich King. I feel that Vrykul would be not only easy to add to the game, but also a fun addition to gameplay. My thought is:

A group of Vrykul have known nothing but sea since as long as they could remember. A lone man, aging into his senility, can scarcely remember his homeland, and the scourge that beset his people, turning them into feeble creatures. He sailed to escape the curse, but it seemed he may not find land before his death.
A crash landing sends the man and his crew flailing toward the shore of the Tirisfal Glades. It is here they set up camp. Shortly after, he discovers that a band of Scourge had defied Arthas' will, the very will his master had so willingly aligned himself with. The Scourge were called the Forsaken.
The man and his crew, more determined than ever to rid Azeroth of their weak cousins, the humans, ally with the horde. However it won't be long before they're swept up in the struggle to retake their homeland.
