This is me too. I had some issues ever since moving to New York from Wisconsin (still using Time Warner Cable both places)... it wasn't bad enough to cause problems until 2.1. Now I get these 5 to 10 second spikes randomly and often 90k afterward. I don't have these issues on any other game. It's not a signal problem, it's not a routing problem, it's not wifi... I really have no idea what is going on. My ping to the game is consistently around 60ms. Late at night (like 1am EST), I have almost no issues at all. It's during the day and evening that the game is practically unplayable for me anywhere that requires a lot of movement (like Titan EX... today was my second time ever getting knocked off by landslide... and then it happened at least 10 more times, not to mention multiple plumes to the face).

I don't want to pull the "omg fix it or I'll find another game" card because I really like this game, but it's not worth $15/month for me if I can't clear content. :/
