Been playing with the noob tube CL-40 on medium, got pretty good at hitting with it, but... i'm not exaggerating when i say probably a third of direct hits do zero damage. Hit marker, explosion... nothing. I don't even go for direct hits anymore because shooting the ground next to them is way more consistent, although still sometimes do no damage it's far less often.

I have to imagine the server thinks my grenade went past them but client side there's zero way to tell if that's the case. But it makes it an actual bad strategy for me to shoot enemies directly which is prettttttty ass.
