There's a small reset in the timing of his abilities whenever he eats a node. Sometimes he can pop off a High Voltage right after throwing out an Allagan Rot or something and it won't be in the same timing as the other High Voltages. We were at a point where this was happening once as it really just depends on how fast you hit phase transitions and where he is in his script, so we had a third interrupt waiting. As your dps increases, you should never see this happening again. At least that's my understanding of it.
