I have Verizon FiOS in Maryland and since around 9/30, I've been getting packet drops resulting in 3 to 5 seconds of no updates, even though my own actions do ultimately get sent to the server.

For example, casting Cure on a party member, but the nothing happens as a result. I cast Cure 2 more times, then finally, 5 seconds later, I see all 3 cures go off, party members speed sprinting, rubber-banding, etc.
