I started playing wow june or july of last year, and made a mage, it's my first and only level 80. I am just starting to raid and get good gear. I'm thinking about starting a tank class to try something new, but I haven't really played many classes and I'm not sure which is best for me. What do you guys think would be best for someone new to tanking and used to playing a mage. I will be mainly raiding when i reach level 80.
