Hi there, Network latency can cause some crazy experiences, like the ones you have mentioned, for PvP. This is because the game connects to a primary host within the game. Depending on your connectivity to the host (ping) you and other players may witness some whacky scenarios. . .like guardians teleporting everywhere. There are pros and cons to both host driven networks an dedicated servers. It's not perfect, but it does allow for matchmaking functionality. If you want, try searching for Bungie's network troubleshooting tips in the searchbar to eliminate any possibility of the connection issues coming from your end. This way, you may confidently curse that teleporting guardian as he or she flies away in the lag spike! :P
