I'm thinking of starting a 3rd character as a RP exercise; I primarily play PVE but may eventually try PvP on the right character but that might be a 4th. I haven't been playing very long, my 1st is an Altmer Sorcerer at level 25, my 2nd is a Nord Templar at level 9. So I'm thinking of creating a character for the DC alliance. Now, when I started the game I had spent some time with characters in EP and DC before deciding on AD. Since I have AD and EP characters, I'd like to go with DC on a 3rd.
The other thing is my Altmer is an upstanding (mostly) citizen that only steals since the Queen doesn't pay well; I'm not planning on having him become an assassin or a thief. I'm planning on using my Nord for some fun hack & slash play style. So for a 3rd character I would like to have him be that assassin/thief I don't have.
My choices for DC are Breton, Redguard, Orc, or, if I buy the feature, Imperial.
So which combination of those races and classes would make the best assassin and/or thief?
