Like I said, if you can completely start-up DC, you were NOT under real pressure.
Are you confusing DC with Warlock Punch? DC does not take long at ALL to start up. If "real pressure" means that I'm getting attacked faster than I can start a DC with, then that's barely worth discussing. I'm not going to wait until I'm getting slapped around; I'm going to use it whenever I FEEL like I'm about to be pressured. As other people have mentioned, MK can reset his position a lot faster than Diddy get set up again with bananas, especially if the Diddy doesn't know where the MK is going to reappear. You already proposed banning it in MK dittos. If nothing else, your "real pressure" doesn't exist much, since MK is the one approaching the opponent, not the other way around. If I'm approaching, I obviously have time to start up a DC when I feel like it, and when I'm getting hit, the lack of serious hitstun will enable me to start an IDC more than you make it seem. Seriously, a MK will not be getting harassed with "real pressure" all match.
You could have done a variety of other things besides IDC to get out of that situation and run to your precious ledge.
Why would you bother, when you COULD do it without your opponent knowing where you are? If you're close to your opponent, the camera angle isn't going to give you away at all. You don't even have to go to the ledge every time. You can IDC to the ledge, sure, but you can also IDC to your nearby opponent, and there's nothing they can do about it. If they try to run away, then when MK reappears (even at the same spot he disappeared at), all the MK has really done is turned a situation into a neutral position. Many people don't think this is fair, and as such, prefer it to be banned. More on that later.
You want a video that isn't of swordgard?
You want a video in which the MK is not punished for using it?
You want a video in which the MK user wins after getting some type of advantage from using IDC?
Fine, here it is.

I don't know why people didn't reference this before, since it's from months ago, but here we go.
Example 1: 0:40 to 0:48. Make sure you stop at 0:48 (NOT 0:49! I'm doing this for a reason), and continue reading. Dojo has been powershielding nearly all of Santi's projectiles. He's taken a few hits, and now his shield is smaller than he might like. He needs to keep approaching. Unfortunately for him, he seems pressured by Santi's projectile spacing, a bomb, a boomerang, and an arrow. He tries side-b, but gets intercepted. The solution? IDC! No more projectiles to worry about. Now go back to the paused video. Where is he going to come out? I'll tell you that he comes out of it at 0:49. I would guess, presumably as Santi did, that Dojo will reappear slightly in front of him, where the camera is centered. Unpause the video. Did you KNOW that Dojo was behind him? I certainly didn't. Do you think it should be legal in Wifi Tourneys too? So much for hearing the c-stick clacking =\
Example 2: around 3:25. This is a point that others have brought up that I don't think you've addressed well enough. In this example, it doesn't even matter that Dojo used it to approach. What's more important is the fact that he wasted Santi's invincibility frames from respawning, and there was absolutely nothing that Santi could have done about it. Enough said.
Example 3, and the most important one: 3:36 to 3:39. Please watch this more than once. I thought Santi was playing pretty smart here considering the fact that he had absolutely no idea when or where Dojo was going to reappear. Unfortunately, it didn't matter. Santi eventually had to land on the ground again, and despite his bomb and arrow, Dojo simply reappeared behind him, getting a free grab right after reappearing. I'm sure he IDC-ed under Santi, eliminating the possibility of the camera giving him away, while staying close enough to capitalize later. Other than guessing correctly and Dojo messing up, Santi had no control, no way of knowing when or where Dojo was going to strike.
You can argue that Dojo didn't absolutely NEED to use it, but why wouldn't he in a tourney? Why choose to approach visibly, stopping to powershield projectiles when he can IDC through them? Dojo wouldn't (shouldn't) bother risking missing a powershield when he doesn't have to.
Now that that's over with, let's finish with this thread, from BOTH sides of the debate.
For the use of IDC: As much as people from both sides say that the debate is going in circles, you people need to clearly summarize this thread. That means straight-up copying-and-pasting questions and answering them completely. This discussion IS devolving into whether or not questions are being answered, so just answer them to the point where there can be absolutely no further questions.
IMPORTANT: This is directly to TOs, or people who strongly believe that this should be allowed. USE IT! You will not be arrested and beheaded for allowing this proposal to happen at your tournaments. You do not HAVE to use the SBR ruleset, even if most people do. That's a risk you take when organizing tourneys; you all should know that. Allowing rules, just like allowing stages, may or may not cause people to come. If you don't like the "official" tourneys because they don't allow IDC, then start your own. You might have less people because you separate yourself from a standard, but that's not a terribly bad thing.
Against the use of IDC: This proposal has been brought up, and people have shared their opinions. Rather than try to flame, spam, or barrage people with points that have been brought up already, just don't go to tournaments that allow this rule. Leave that to the people who want it to be allowed, and stick to a rule set that you are comfortable with. Having more people on one side agree won't make the other side go completely away, but nobody's forcing you to press the issue to its fullest. If you don't like it, say so (which people already have), explain why (which people already have), and wait for a response. If it doesn't suit you, you don't have to spend all your time pushing the issue your way.
Both sides have said some things that weren't completely clear, but
I don't think that ANY post after this is needed, EXCEPT for an UN-BIASED SUMMARY of the points. This summary should be able to be seen by possible TOs, and it needs to be up to
them, not the people in this thread, to decide whether or not to implement it in their tournaments. After all, it's the "SBR recommended Rule Set." Don't like every aspect of it? Don't use every aspect of it.
EDIT: About the "seen by possible TOs thing"... maybe a sub-forum or updated thread somewhere of proposals like this which modify parts of the recommended rules set? It might get crowded though.
