I think this post conducts interesting additions that should not be left out by the game devs. As for the staggering movements that the game physics brings us... the devs at Bohemia Interactive would have to generate a whole new engine to produce a non-glitchy movement. And we all know this game is a port from Arma II and they are not willing to pay the devs a few hundreds of thousands of dollars to remake a whole new engine. so sit tight and wait a few years until DayZ 2 comes out with a new engine.. if ever. I also prefered the old inventory style... the new one is overwhelming. You actually needed to be smart to figure out the old system. Which kinda pwned the noobs for us right off the bat.
