LOL i hate it when that happens LJ
last time i went i goted bout 5 hits and i shouted out hit, then as i was on way back to safe zone i realised not one hit me, even tho it was only from about 5m away i just assumed. that was a bummer
as for the pain factor i think it all depends.
point blank range they can hurt, but again its the sort of pain that goes after a few minuates.
i got shot while marshelling once right behind where the VFORCE mask end, so it hit me in the back of the ear, the dude was bout 10m away, it was probably an accident but neither of them owned up to it, anyhow that cut the back of my ear and that REALLY hurt for about half the day.
