D2s server systems are so trash that for 75% of a crucible match most of the players were invisible to me... including myself for a while. For a bit I was a floating handcannon, then for a while my shotgun was invisible (with weird shooting animations and sound effects to boot). I'm on the verge of quitting crucible outside of my own country's high traffic times because these servers are so unbelievably worthless. It's not PvP, it's PvPvS, because if you haven't got the server advantage then half your shots won't register, and you'll lose every melee or super engagement too.
