Weird Latency issue.

[psway]

I have had the game installed for a long time now and have never had this sort of problem. However the past few days I have been having a latency issue where the % on the latency meter drops to about 95% then goes back up to 100, this occurs for about 2 seconds. The problem is after that it is like I am out of sync or not connected to the server anymore. I can move about the game but if I cast or auto attack it becomes stuck casting. The funny thing is it reads 52ms 100% again.

Any insight?
