ok first of all, SLOW OWNS! it's like having frost for kiting. i can kill lvl 71s without them ever touching me. pyro, fireball, now there at 30 yards so use slow, use another fireball and if there still alive use scorch. if they have crazy health frost nova blink, run to 30-35 yards and repeat just without the pyro. so who needs frost!(i was frost to lvl 65 so no offence to anyone) slow is like frostbolt(with permafrost), it slows them by 50%.
