This has been a persistent and annoying issue. I always play the MSQ with my wife, so needless to say, we need to be in the same instance.

-We cannot use our rings of eternity to teleport to each other
-The very first zone required you to talk to an NPC to zone in. This required us to repeatedly zone in and out until we got lucky enough get into the same instance together.

Then today, we go to resume questing in the Ruby Sea. I log into instance 1, she logs into instance 3. We're not far enough in the MSQ yet to be able to walk to either the Azime Steppes or Yanxia, so I had to go all the back to Kugane just to get into the right instance.

Please tell me there's a solution coming for this sometime soon? My wife and I shouldn't need to spend the first 20 minutes of our gametime zoning in and out until we can actually work together.
