This is a streamer that i usualy watch while leveling.
www.twitch.tv/khandz he is a swedish dude with great experience with mages and he also awnsers questions that pepole write in the chat. Its also a nice stream to have in the backround since he plays great music. He was the first mage that i saw on the horde side to get level 60 and he also got 100% mount that he farmed while grinding.
