Constitution is still generally regarded as a stat that helps mitigate critical hits. It's been, at times, suggested that Con bonus / 4 provided equivalent crit padding, but I believe that's been disproven. Now the wiki only suggests Con bonus will help but doesn't specify how it will help. And I haven't run across any data that clearly shows a crit reduction effect from Con bonus.
Is this just a myth at this point? Or can anyone show with data how Con might provide some crit reduction?
