Backstab = 100% critical chance while behind the target, a must have for every Scoundrel IMHO.
Passing behind a target while in combat is fairly simple with a dext character as your movement should be really high, takes 1 AP to 2 AP if the target is really big, all that for a 2 AP critical attack.
You don't trigger any Opportunity attack from the target, but you may trigger it from other opponents, rendering the use of Tactical Escape or Battling Ram-like skill a great help.
Don't forget that backstabbing only works with daggers and knives ... Don't pick it with if you are using a Warrior 1 handed weapon.
Edit : Might be worth mentioning that if you miss a backstab, there is a high possibility that your target will turn to face you (even if I don't understand why it would be so, it is ...)
