After a game of getting heavily friendly-fired by would be ranged kill stealers, I was kicked from the game at the last boss for taking too much damage (like I’m running to a lone Stormvermin with my 2H hammer and the elf launches its ult in my back - sort of thing happened multiple times).
The occasional arrow in the back will make your character say a line, but with constant FF he seems to be resigned.
Constant whining from the character himself could make it obvious why you’re losing health. Right now you can just empty a quiver into someone’s back and make him look like a bad player.
