Just make sure that the 2s average RTT you have just posted, is not at the time of heavy network usage by other applications. (like video streaming, downloading or torrent-like P2Ps)
You could also check and see if you have same problem with famous IPs, like 8.8.8.8. If you have, you can go yell at your ISP confidently.
Some kinds of internet usage (Like playing a MUD) are affected by network delays much more than bandwidth. In your case, the 2s delay makes it almost impossible to play CF. I have same issue at times too.
