You've got to remember tho, that soon, our cleave is going to hit for 40% less. So the idea of throwing in an obliterate on the 2step means you're going to get one less Necrotic strike, but also that you're hitting for more single target, on top of the free proc off rime for a free howling blast. Since our cleave IS being reduced, the only real bonus of popping howling blast over and over is the range and the snare, which will still be applied on a decent rate via the proc and the dc spam is just an idea for those who seem to perpetually stay at range
