Uhm. No. They don't.
Foresight increases the physical defense by 20%. Its just working for physical damage and 20% defense up is not the same as 20% less damage.
The other two you named reduce any kind of damage (not only physical damage) by 20%. Thats a very big difference to Foresight. As WAR is completely different in this kind of "any damage" handling, I don't expect it to get one of the "Role" Skills.
