Why I voted yes
I'm disappointed with this thread. There is no reason to belittle your opposition in a debate.
As many have noted, I voted "yes" in this poll, in favor of banning critical hits. My vote was a genuine vote. This is my reasoning:
If we have decided that it is our policy that game mechanics are not the most important factor in determining rules (in other words, if we've decided that we can change the mechanics of the game), then there are parts of the game that I would like to change. One of those parts would be critical hits. I would favor a game with fewer elements of chance in it.
Some claim that voting not to strictly following game mechanics doesn't imply this. They say that only obvious glitches that ruin the game will be banned by that, things such as acid weather and classic sleep clause. We won't use it for anything else, so they say.
But we will. Based on discussion results, we already have. Cartridge sleep clause does not break the game, and it is not a glitch. Acid rain, by all accounts I've heard from people who play WiFi, is pretty underwhelming. These bans are not based on logic and competitive spirit -- they're based on fear and 'consensus'. Fear seems like an unlikely motivator in Pokemon, but it's a fear of change and a fear of the unknown.
Rationally, we recognize how difficult it is to know what a 'glitch' is. Is it a glitch when Thunder hits through Protect in the rain 30% of the time or intended behavior? A frozen Pokemon using Sacred Fire or Flame Wheel defrost themselves when they use the move, and then they hit the opponent. If a frozen Pokemon is confused and uses Sacred Fire or Flame Wheel, however, then it has a chance to hit itself in its confusion while still frozen and fail to defrost. Is this a glitch?
A sleeping Pokemon that uses Outrage, Thrash, or Petal Dance is not locked in and won't become confused, unless that Pokemon's Shed Skin activates, in which case the user is locked in. A sleeping Pokemon that uses SolarBeam, Razor Wind, Skull Bash, or Sky Attack is forced to remain in the turn after charging up, and unless it wakes up that turn, will fail to do anything. Which of these are intended behavior, and which are glitches? What would the intended Ice Ball / Rollout mechanics be with sleep? Should Hyper Beam recharge if you KO a Pokemon with it?
These questions, among others, may seem minor, but I would say that they are more likely to come up than some of the objections people bring up in other topics against being strict mechanics supporters. Lum Berry Wobbuffet being faster than your Pokemon with a sleep move, switching into it, and then using Encore and switching out to get a win? This is the proof that cartridge sleep clause is flawed?
We rationally recognize how difficult glitches are to determine, yet still rationalize mechanics changes based on the idea that they're obvious. We say the exceptions will be few, only in extreme cases of obvious glitches, yet change things that are neither exceptional nor glitches.
My position still is and has always been that we should strictly follow game mechanics. However, if we have decided not to do so, then we cannot use adherence to the rules of the game as a reason to block changes designed to make the game more competitive. Removing critical hits would make the game more competitive, therefore we should remove them, and that is why I voted "yes" in this poll.
