float on air trick : Legacy FPS / MMORPG / RTS Discussion

well this happened the other day: i was on a pipe on side of a building and a guy stunned me and i began to float on air and was able to stay up there and attack! so i repeated the process and it worked again.

These things dont usually work anymore, the old one was get on a pipe and do /sit . there was also another that i think still works, get on the pipe and eat the merovingians cake.
