I have a good connection, (50/10 mbit), and a good enough latency (~28ms I believe) in europe, although I played on NA server when ARR came out.

Now, I have some friends on Goblin (NA server) while I'm on Shiva (EU server). Lag in game it's fine, I don't care outside of dungeons, I do care inside.

How's the lag if I migrate to a NA server? It would be really interesting if I can migrate to Goblin and be able to play, I have a good guild waiting for me there.
