I'm sorry?
I just meant there's entirely too many topics on Steam proper about it, get's tiresome after a while.
I meant no ill will towards anyone here.
My official stance is that they're entertaining when I/my team benefit, but annoying when I/my team get random-gibbed.
On the whole I think they make TF2 unique, while not a strictly beneficial element, they add zaneyness to an industry otherwise run by graybrown shooters in graybrown maps.
I'd like to think that Random crits let people grasp victory from the jaws of defeat just as much as they infuriate the recipient and randomly lose games for people.
