You're in denial. Guard need a fix. Ranged classes get easy win because of that.

Why do you think they introduced guard crush in fighting game. It's to prevent to round to be too long. At 329ms is like guard doesn't even have any use at all.

Guard depletion makes sense in duel. Although for large scale fight, it doesn't make sense. You also have to consider the position where I got my guard depleted. Based on online desync I died before my FG animation ended.

You misplayed, you made a mistake and you got punished for it.  Everyone should be punished for walking into 5+ sources of damage, that is called working properly.  If there was "gaurd crush" as you suggested, there would be 1 player just spamming guard crush and everyone else would be spamming DPS.  The one spamming guard crush would likely be a DP meme player.  Guard Crush wouldn't be a solution, it would be worse than it is now, because 2 sources of damage would delete you instead of the 5+ that it requires now.

It gives you an overview how fast it is.

You got caught, I see nothing wrong here.

You're basically sharing to the world that spawn camping is a good thing in RBF.
