I completely forgot who posted it here, but somebody on DBO managed to get a sniper headshot on an opponent through the ridiculously tiny space between a box and a wall on Bannerfall. That was a thing. ;-)

People will do whatEVER they can to hide every single part of their body that they don't need exposed and just camp like a...well, you know what. I've seen people find a way to stick their sniper barrels through walls.

It sucks, but it's common.

I just got killed by someone that was somehow standing on the side pillar right in front of the A special ammo on Pantheon. This made it so they had an elevated position but were almost completely shielded by the pillar. I didn't think that was possible or at least no suppose to be possible. Is this a thing or did this person manage to wedge himself just right to get an unfair advantage? I marked it as cheating either way because I've never ever seen that before.

Yup. Saw that a lot back in Year 1 Trials. No fancy tricks, just jump and crouch on the pillar. Not sure why folks stopped using it (maybe it got too predictable), but it's definitely a classic sniper pillar (not cheating).
