Now i've seen multiple ganks that got 2 pyros just spamming it.
I would suggest just increasing the damage and not an instant stagger of the enemy as it is quite OP if you got 2-3 people just spamming it and someone with a crystal soul spear.
Of course you can say "git gud" but does it improve it being spammed in ganks?
I wanna see you try going against 2 pyros spamming it while one is pressuring you with a sword as a meele build that aims for parries.
If you can do it without any help, I'll accept it and will try to "get gud"
