regarding rogues, I have some ideas:
- Each weapon has a backstab value. This means you get a bonus to attack and damage when you attack an enemy from behind. This value is 0 or very small for some weapons and very high for others (daggers maybe).
- Rogues have a talent that the bonus is higher for them and that the bonus is even higher when attacking from invisibility or stealth (the new backstab talent)
- Rogues can have a talent that they also get the damage bonus when attacking an enemy who cannot defend himself (like stunned). That is the "coup de grace" talent from DA:O.
- Rogues get a skill that they can move behind a nearby enemy without provoking an attack of opportunity. You can do this even if you could not go there normally but there must be some free space behind the enemy. (means for example you can do it when you are surrounded. I think of something like climbing or jumping over the enemy). If it fails you suffer an attack of opportunety and do not move, if it hits you move behind the enemy and if it is a critical hit you move behind the enemy and deal some damage.
