I friend of mine has a DK that uses a lot of dots and he can burst down people in matter of seconds. I was also very surprised how he destroy me in a 1v1. The damage is insane, imposible to resist. I was not abble to get close to him, because he was surrounded of dots all the time and if i stay a few seconds inside of the areas my health was going down very quickly. I could win to him only with my sorcerer from the distance.
I think the main skills he uses are eruption, elemental blockade, burning embers and ferocious leap.
Now the question is: are sorcerers capable to do the same? can anyone suggest me a good build for aoe damage? is better DK than sorcerer for this kind of gameplay?
