As stated. Willpower is useful resiting Psi...
Thats not the end of it though. Should your caharacter get captured and tortured, you would use it there to see whether they cave in under pressure.
What about those negative attributes where the character has to try and push past a phobia or anything where mind over matter is important, you would need willpower to stay on the course and see the task through.
Willpower is actually quite important, it shows simply how mentally strong your character is.
But you are right until you need it you will find yourself wondering what all the fuss is about... Right up until you fail a tast for the lack of it...
