Going to a semi-high traffic area...
I'm on a PvE server, so if you're on a PvP server the flagging part is not necessary.

Anyway, flag your one non-stealth toon.
Have them sit down, via "x".
And type /AFK.

Then actively watch with your stealth guys.
See if anyone wants an easy and unfair "free kill".
They cannot complain if you get an easy and unfair free kill.
