The problem with crits in tournaments is that they can decide who wins with skill taking no part in it. In poker luck determines how strong a position you are in and you then use skill to carry through from that position to win, even a weak hand can work well for you. In TF2 skill determines the strength of your position but a simple crit can wipe all that away and hand a win to the other team regardless of who was the better player. It's the equivalent of having poker players roll a dice when then they fold and they are automatically all in if they roll a 6, the luck is unaffected by their skill.
You either did not read the entirity of my post or didn't fully understand it. I addressed this issue already and in fact stated outright that crits being overly deadly is the reason they're not appropriate for tournaments.
My apologies if I misread your post, I haven't slept for over 24 hours and am currently running purely on caffeine.
Actually, the statement he made was the
point of crits, as Valve said. They're to occasionally reduce the influence of skill. The idea was that a newbie would never, ever have any chance of taking down an experienced player, and getting killed constantly is boring. Knowing this, Valve made it so that there's a small chance of getting a crit, so that a noob can occasionally get a kill on a player he would normally have no chance against. Sorry to say, loosing ISN'T fun, (except in DF) it's the CHANCE of loosing that makes WINNING fun. If you couldn't loose, it'd be boring, but an impossible game is just as boring.
