Yup, 4e is my preferred solution...to swingy crits, and other problems!This... or run 4E.
we all know it's bound to happen that one person/character in a group that just always happens to get that elusive 20-20-kill at the start of the boss fight and what was suppose to be an epic battle turns into an anti-climatic loot fest on a boss that you probably created yourself and put your sweat and blood and the souls of your last group into to be at least a challenge to beat.
How do you as DMs/GMs overcome this anti-social behavior?
Yes, make with the public wailing and gnashing of teeth. Players love thatLaugh.
Congratulate the players and bemoan your evil bad guy publicly; but never blame the party for good luck. It will quickly become the story the party loves retelling the most.
....
At the very least, have the 20-20 trigger a Fortitude save like Death By Massive Damage. Otherwise, even ignoring villains, PCs can get one-shotted without getting a word in edgewise.

You could just update the rule to be 0 HP and staggered all the time, but whatever works for your game is obvious fine.well we do have things that can help prevent the 20-20-kill on the players, DM favors for example. I did a 20-20-kill on our cleric crusader, they asked to for a DM favor and I dropped it from a kill to 0hp and staggered and they get me a soda or what ever is needed at the time. Although I'll think on that I might make a fort save of 20 or 25? since 15 is the DC for massive damage, but an insta-kill should have a higher DC right?
