Pay attention to damage dealt after each hit - after dice slightly nerfed g43 and selbstlader 1916 a while back depending on range it could be 1headshot+1bodyshot or at a longer distance might need another bodyshot
Ok, so you're struggling with this for half a year and didn't bother checking the network graph?
DNS has fuckall 2 do with how the game runs. And finally I'd familiarize with what packet loss is and why it might be a bit of a problem.
Yeah always wondered 'bout that as well, weapon skins i can understand i guess - you can see those at least but appearance skins you never even see...
Unless of course you're really loaded and don't have anything better to spend on
