"After the end of the faction-specific starship tutorial area (around lvl 4-5), players are finally allowed to set foot on the world of Nexus. The problem stems from the fact that, based on what race you have chosen, your characters arrive in different starting zones, and sometimes even different locations within those starting zones."

That's not true. Each race gets a breadcrumb quest to go to a particular starting zone. BUT, you can still choose to go to the other starting zone if you prefer.
