I don't know if it's okay so here
On vsh there are some maps that has vents that require you to crouch, so someone told everyone to go demo with loose cannon and camp in the vents which I don't know if it's fair or not but the question is isn't hale supposed to be immune to any kind of knock back when crouched

I'd probably have posted this in Team Fortress 2 since this seems like a general question and not a suggestion-- maybe someone reading this who is able to will migrate this thread :)

While it is true that Hale takes far less knockback while crouching, he is not immune. Weapons designed with knockback in mind such as the Loose Cannon and Force-a-Nature are still decently effective against a crouching Hale, especially if there's multiple of them at the same time, such as in your example.

It sounds like you were the unfortunate victim of coordinated teamwork, which is hands down the most powerful strat in VSH. Luckily, this doesn't happen very often nowadays.
