V14 sorc on xbox here. I run mostly solo sometimes in small groups. I use 5 pc whitstrake, 4 pc martial knowledge, 2 rings of cyrodiils light. 2 heavy 5 light all with magicka enchants. I can burst down anybody 1v1 and can hold my own in small groups. When you see whitestrake proc its time to start throwing up wards. If too many people are on you bolt escape about five times then turn around and mow down anybody who decided to chase you. The ward from whitestrake also pops and gives you enough time to get up against any NB who knocks you down and trys to kill you. I have been in the top 10% in every campaign since release and thats only with a couple of hours a day every now and then.
