Guild Wars 2

If I change server from EU to NA, what kind of ping increase should I expect to see?
I’m located in Denmark, Europe. I’d like an estimate as to how much I should expect to get in latency if I switch to a US server.

It’s going to at least quadruple. But you can’t know without doing it.
US uses Level3 in Dallas TX.

I live in the UK and play on an NA server, no noticable difference when just running about. Slightly laggy when in a major event, but nothing whcih should cause any real problems

Doing some self-testing on speedtest servers I have ~45ms to Frankfurt, Germany and ~153ms to Dallas, TX. Can I expect this to be similar in GuildWars, or are there any hoops I should be aware of? I can live with 150ms in an MMO, but anything above that is too much.
