We're open to suggestions, just write what you think would make a good class (including the names for the post counts) and then people can comment on that. The biggest work is done (changing the software to support the idea), adding or tweaking a class or two is painless.
Here are my suggestions for a Rogue class (or Survivor class, if you prefer):
10 - Street Urchin
or Gang Member
or Goon
100 - Swindler
or Thug
or Smuggler
450 - Brigand Captain
or Outlaw
900 - Master Thief
or Desperado
1500 - Assassin
or Crime Lord
or Felon
If you prefer to use the Mage/Warrior scheme, i.e. there are only 4 steps, one of the above can simply be left out, of course.
