Sadly, that's only happened to me a couple of times - one of them was for the border-line unfair Burly build that I mentioned earlier, to which I responded by going Nimble and kicking just as much *** as I had as a Burly. Of course, their response was to call me "gay" for using OP weapons (the Gatekeeper, in this case).
Sooo... yeah. Haters are indeed going to hate. But **** 'em, I had fun even if it was at their expense (good players never seem to rage about dying).
