I think the Thief class should be renamed to something like... Rouge... alot of people are misled to think that people that are stealthy and nimble are obviously thieves...
A thief is set on thievery... but giving the name Rouge... it can give much more versatileity...
Examples...
A Warrior can be called such things as: Knight, Myrmidon, Fighter, etc.
A Sorceror can be called: Summoner, Invoker, Wizard, Mage, etc.
A Priest... o boy... err...: Cleric, Cultist
, Healer, Acolyte, etc.
A Barbarian... jeez lol...: Master of Arms, Armsman, er... you get the point...
But a thief... (hard to think of one) well i dont know any...
Just my opinion
