I use ignore pain just for safety measure so I don't have to move or avoid damage. If you actually read my post I said I used EQ and wotb ALTERNATIVELY.
You really don't need any other hitting ability since everything dies to one cleave. You kill (and run, with marathon) so fast, your wotb will be on cd half the time, but with EQ you always have a button to instakill an elite pack.
Don't really need any more mobility when you can spam sprint, really, and charge actually does not allow you to run that much faster because of the animation lock afterwards.
The alternation maybe faster if you can kill white mobs without them taking too much time up. Since the longest part of ww build is killing the actual elite packs when wotb is on CD.
