I'm fairly certain at this point that you just refuse to admit that you were wrong.
Rather than look like a fool for admitting you are wrong about the SA on crawl, you are just going to bash any post that is attempting to show you why this is a useful tool.
OOS options are limited. The amount of options you have out of tanking a blow is well beyond the number you are given OOS. OPTIONS ARE A GOOD THING.
Even if DS doesn't play Boozer, he has proven himself to be a much more knowledgeable player than you seem to have. Knowledge is power. It doesn't take much to see that something that gives Bowser more options to punish opponents than shield alone could ever do is a good thing.
Tell me how you punish an attack that is safe on shield, but able to be tanked. For somebody who loves their shield so much, I can tell you that a player using the crawl armor is going to be punishing their opponents more often than you are without it. Some attacks are either too safe on shield, or don't give you enough of an advantage for your OOS options. With crawl armor you ignore shieldstun, can punish a wider range of attacks, and punish with a wider variety of moves. Badguy is talking about landing an Fsmash out of crawl. Good luck ever getting even remotely CLOSE to that kind of punishment OOS.
In a missed tech situation, crawl armor is probably going to be highly valuable. Not only because you can punish with essentially any move you want (Fsmash and Down B for insanely early kills for example) but if you predict wrong, you still have so much freedom compared to if you held your shield as they missed their tech. That's one situation, and if Boozer players invest more time into the crawl armor we are going to see many more circumstances in which tanking a hit is one of your best options.
