I'm confused by this post. Can't you just walk across the bridge? I don't get what you're trying to say. And if you're not happy about the realm you end up in get into your spellbook, pick one you like, then tell the book to always put you in that one. You don't have to leave it random.
Ok, I can't think of any witty reply that might not be taken the wrong way for an opening line.
One way to help avoid the lag is go into your options, to the icon at the top that is marked gameplay options 3. Open that tab and at the bottom of the list you will find the line "Remember Realm". Toggle that to yes and hit the OK button at the bottom to save the setting.
This works to keep you in the same realm most of the time. If you do things like castle tours or join a team you will land in whatever realm the other player(s) are set to. Which can be positively painful if you land in front of the join a team kiosk in Old Town on Ambrose at a busy time of day.
