Just got done beating a 69 paladin in arena. It wasn't even close. The feeling after I won is one of the reasons I play WOW. Don't really have a topic, just felt like doing a little bragging and sharing after that win. I'm a lvl 66 frost mage. Elemental with ice lance is killer. She poped her bubble as soon as i summoned elemental. Once she popped her bubble I just ran away from her conserving mana until it faded. Then I blinked close to her - frost nova then ice lance - frost bolt. COC after that to slow her then ice bolt - fireblast then nova again and repeat. I only lost about a 1/3 of my hp.
