i had lag issues when i had a bad PC - got a new one..all my lag issues went away. The thing is, OP, "lag issues is SE fault!" isn't always accurate, everyone should suffer from lag issues if it's purely SE's fault - It's been reported ISPs handle XIV data stream as P2P which a lot throttles to try to deter torrenting. The one thing a lot of people seemingly refuse to do is check with their ISP about throttling which can and will cause lag to happen in this game.
