Up until now I've practically avoided Maul's force push, but if you dash spin through a group, turn and use it, you'll kill just about all of them before they turn around.
Maybe I'm late to the party on this, but I just got a 41 kill streak with still 500+ health left.
Hmmm... going to have to try that.
I do this sometimes, but it leaves you open to enemy fire. I usually Spin Attack and swing during the ending animation, which, to some, it looks like a one shot.
I do that primarily, but if I'm too far away to strike after the spin, I use the force push, if i know there's no one behind me.
I don't like starting with it bc the animation takes long enough that enemies can eat into your health.
