Dear RottingWood, after reading through your application, I can't help but notice a few oddities that contradict lore.
First point, the infamous Robin Hood does not exist in the Warcraft universe, but rather in our own timeline, and so it would be illogical for him to have a brother that does exist in this fantasy universe.
Second point, Arthas the Lich King is quite dead, and while it would theoretically be possible that Rottingwood participated in his vanquishing, we tend to stay away from such things for our own characters, as everyone could go around claiming he was the one that killed Illidan or defeated Cho'gall--to give an example. ^^
Once you have read up a bit on Forsaken lore on places like these http://www.wowpedia.org/Forsaken , http://www.wowpedia.org/Forgotten_Shadow and of course our own website, you are very welcome to try applying again.
Good luck!
