I have seen this done on Sacriel's stream a bunch.

Get 1 person to sprint into a point on any barrier (wall, fence, etc)
They are now "sprinting on the spot" about 2-3m infront of the wall they ran against
Now, get a 2nd person to sprint into the same point on the wall as person 1
Person 1 is now ejected through the wall

Must be a DayZ noob who made this thread - DAYZ always leaves this up to the servers. Different servers for different people. PVP, PVE, Role Playing, 1st person, 3rd person, both, whatever. It will be added as a server option soon, its already been reported.

Don't waste the feedback teams time with these sort of posts.
