Not even a year ago.
It might not have been a Glock, but the fact that I sprayed someone with an MP5 at close range (10 hits, confirmed by the console, aimed at the back and head regions) and they turned around and killed me with a pistol (or, rather, that they should have been able to keep playing after that) is stupid as hell. There's no reason they should have been able to survive that, armor or not.
