I have found an easier way to form party with a level 90 character when you are lvl 1. When you make a character you use a girl's name and it immediately becomes much easier to be in party with a lvl 90th This can be used to cross realm zone invite your main level 90 to farm Onyx eggs or rare mobs on a low population server. (To do this you need two accounts ofcourse, or a friend that can help you.)
