Oy my god, I hate that dose of spastic mouse that you get randomly in the game!
It never happens when you think it will, and sometimes it just goes nuts for a small time... Funny afterwards, but annoying and frustrating while it happens. I don't mind dying if a zed kicks the crap out of me and my team cos we just weren't able to stop them effectively, but I despise dying not through my own lack of skill. For example, grenade glitch, spastic mouse (yes that is the technical term
), team blocking a door, player join late and remain AFK, etc. Sucks so bad...
