The default graveyard is at your faction's floating rock. You don't go to a base.
In other words you can run through the bubble like you would a door. Kill yourself with hellfire, run through, rez.
Except here, you have to be quick otherwise the spirit healer will cast their AoE rez on you before you make it back to your corpse.
hope that cleared things up. (btw, you don't need to lifetap, it's just faster that way)
And to the "Then you start with no health" comment...
Do you not know what food and water are?
