It's one of those things that sounds good in theory but practically speaking there are some potential problems (that others have pointed out).
Seeing as we don't quite know how it will work we'll just have to wait until the game comes out before deciding.
My personal opinion, it'll be somewhat useless for the same reason it was never used in Red Faction (the original this is), which would you rather have?
A- A partial resistance to bullets from one direction but be forced to run up to everyone and bash their brains out slowly?
or
B- USe a long range firearm and just kill them there on the spot with minimal fuss?
