The point is, It gives you something else to do.
It made me have to rebind the NPC button. The purpose of unbinding it was, back when I did CPQ, I'd be typing whilst my leader went into CPQ. I'd hit space, and the NPC would activate, sending us all instantly back out, and getting everyone mad at me. It forces you to have that button set, which is handicapped. I'd bind it to an unused key, but hell I'd hit all of these at some point.
