[sblock=Hrav's Plans]I absolutely plan to have Backstabber be my 4th level feat. I really wanted Intimidate, though - I didn't feel quite right starting without it, but couldn't decide what else to drop. It absolutely fits his character, though, so I made sure to get it at 2nd level.
With Backstabber being Hrav's 4th level feat, I'll probably take Nimble Blade at 6th level, unless I see a fighter encounter power swap that looks like a really good idea.[/sblock]
