I had a scout for a long time, but came into him at around 17th or 18th level (that was when the class came into existance) so I have a skewed view on it. It has the same drawbacks as any of the other hybrid classes (templar adept) at low levels, so you'll never be as good as the pure classes at their particular speciality. I will say that you should decide not so much on "OMG it'll be so cool that I can do this by 10th level" but "I envision my character as being the type that would do that". If you see your character as not so much a toe-to-toe front line tanker but more of a flanker who works with tank fighters alot, but still needs to be able to fight his way out of solo encounters sometimes, scout is great for that. If you are the type who is gonna wanna get in people's grills all the time, not so much. Or, if you are the kind who wants to make slashing attacks along the enemy's rear while your friends are getting in their grill, then straight rogue is hella sexy. Can't emphasize enough, though, pick your class to match up with the kind of character you want to be, not the way you can get the maximum anything for your build.
