Another Reason not to PVP

The reason for this decision is because of how important latency is in PvP. We want you to be making the choice of switching to what is potentially a higher latency realm if you want to PvP on that realm, rather than having you randomly placed on another gateway that could mean you have a severe disadvantage.

As far as I know you should be able to PvP with your party members that are in different gateways. Just make sure you are in a party together in the same town.

Other games that support multiple realms either:
a) Do not allow you to play PvP between the realms.
b) Have exactly the same latency issue where some people are lagged due to their distance to the server.

We happen to allow people to switch gateways if they understand that their latency will be affected and still want to play against a specific queue.

Once we have enough player concurrency to have full queues on all the gateways, this won't be an issue.
