Well I was trying out some things with the way I click the portal doors and I discovered...
If your like me there is no hurry at the door. I use a door to stack all the slaves on the main (like walking into a corner). Before I make the zone transfer. Just for the sake of realignment
If all the team is aligned well then a swift double click will almost always transfer the whole team to the next zone
It has something to do with the zoning its self it messes with isboxer's broadcast or something
