I would like to add my voice to the large number here. I think it's clear that almost everyone on Master Del'Nara would be happy to merge with the PvE Oceanic server but it seems like you do not wish to mix those server types which is a reasonable decision.
If that is your choice, then the only reasonable option is to let us transfer to the US West servers (US East has a much bigger ping for most of Oceania) or give us a choice of the main servers to transfer to and let us decide.
It is not fair to the players to leave us waiting 15 minutes in a warzone queue and because the wait is so long and the time is unpredictable, as the match might finish early, we have to make sure we are watching the client every minute or we will miss the next game and have to wait all over again. This happened to me last week while I was tabbed out to read the forums. I missed three games in a row and ended up waiting 45 minutes for a game.
I was also involved in a high-end PvE guild which quit due to lack of content - another issue but I won't address it here. The lack of content has made many PvE players leave and as such has made it difficult for many guilds on Master Del'Nara to run the new operation. A transfer or server merge would obviously help.
I will echo Locknesslady's sentiments: Please let us know as soon as possible if you agree and will let us transfer or if you are unwilling to do this. Your paying subscribers deserve to know.
