Major Vigor, how much health does it give?

I was curious as to how much the Major Vigor rune actually gave after the -50hp. I've had 2 guild mates, one say 16 and another say 46. I believe for me the minor gives 30hp. So does the major vigor give more health than the minor? And does the amount of health change for each class?

Minor: +30
Major: +41
Superior: +50

It's the same for all classes.

Conclusion: Superior Vigor is not worth the cost.

I unlocked Sup. Vigor using faction, but I will never buy one.

I've been quite surprised at how many times I've seen, or been sitting in that nine health differential when I've been PvPing, and actually come out alive. It's worth the cost if you have to money to buy one.
