Nooooooo.
Blocking will DEFINETLY be in the actual battles and stuff like that.
As for in cities when you're in a hurry - Not a bad idea. Because if a guy with a car starts plowing through a crowd - Not pretty and the outcome will be suspension or ban if constant reports happen of this.
I've never played a FPS that had no blocking. I'm pretty sure even N64's GoldenEye had blocking.
All I'm saying is - that there is NO way in my many years of gaming will combat have no blocking. It's an insane idea to do so.
