I have had this lag issue with teleporting, return port and receiving guild support, just recently um about a few weeks. Not only do I lag myself by doing these three things, but also other players who teleport around me make me lag too. I'm not sure if the nvidia driver of my card which is the latest version or a recent patch thats causing this. If I restart the game it does fix this problem, but still its annoying. Just wondering if anyone else is having this same problem.
