Well for starters, Kel in any build can be bursty but not to its full power if picked wrong talents. For example, Glacial Spike can be used for 1v1's or for Aoe damage as you need 2 targets with chains to make it stun, the spike counts as a target but obviously the target will only go to it. Power of icecrown can also make you deal MORE damage! But you will need to effictivly use chains and ice nova to the best to gain the max 30% more spell dmg. The Damned return doubles your Death and Decay. That is all that is need to be said about it.
