Undying will needs to go

There is not much i can say about the undying will modifier so that my post won't get removed for being excessively negative.

This modifier just need to disappear, it is nothing but a nonsense time waster most of the time, forcing you to skirt around enemies waiting for them to become killable again, and total BS some times.
I just died because of it, the situation was that enemies started pouring out of an abyssal pit in seepage map, which is narrow hallways, they surrounded me in a blink of an eye, they were packed so tight i couldn't roll out, and one of them happened to have undying will, i couldn't kill any of them and before i could harm them i was dead.
