Maybe not that often, but no matter how good someone is at something, there is always a chance of failure. Always. And even right now, no matter how good of a fighter you are, there is that 1 in 20 chance of failure. Why isn't it fair that skills recieve the same treatment?
"Always"-you are making an absolute statement here, and thus, if an example can be thought of where there is no chance for failure, you statement is falsified. (I am not bothering to type a complete situation out as I am quite sure we can all think of some.)
Secondly, just because there may be some chance for failure in some situations, that does not warrant that their should Always be a 5% chance of failure. Perhaps if a circumstance occurs where it is much more difficult to perform a certain skill, a penalty to the skill check, or a DC modifier should be implemented (*looks and PHB ... wow, a system already in place), thus creating a variable chance of failure.
And considering all the cheap +skill items and other crap, yes, I definately feel critical failure needs to apply to skills. I'm tired of all those rogues automatically succeeding at everything that they do.
Foremost, these cheap "+skill" items were a bit of a mistake, and are being dealt with in "3.5". I also have been witness to multiple rogues failing in many different skill attempts. They get more possible skills, not higher limits on their skill ranks.
And while 1 in 20, or 5% may seem harsh, it really isn't. Players rarely roll skill checks, especially compared to saving throws and attack rolls. Yet those have the 5% failure chance. And look on the bright side, this also would mean there is a 5% chance of automatic success also.
I do not like "banking" on a 5% chance of success... And the frequency in which players will roll skill checks compared to Attack rolls or Saving throws depends on the campaign/DM... if that were even an effective argument in the first place.
The automatic chance of failure or success from those rolls comes from the "inherently chancy nature of combat," and that simply does not apply to many situations where skills would be used.
There is no problem with implementing those rules into your game, but I think it simply unnecessary.
Also, remember, a natural 1 on Attacks and saves is "automatic failure", NOT "critical failure" unless you implement that house rule, which I find detestable. “Yay, I am a HERO, and I have a 5% chance of COMPLETELY flubbing up ANY attack I make!…. Yesterday, I broke by sword, today, I shot myself with an arrow…” While this can be comical at times, it is usually not perceived as such by the “victim” and serves to detract from the idea of the characters being heroic or legendary.
