Does anyone know the formula for Hoplite's Pierce? How good is it?

When I use it I see a big first hit followed by 1-3 smaller hits.
How does it scale with physical damage?
Is it any good? I have no ideia if I should invest 15 points in this or stabbing.

I think Stabbing is better as you can continuously attack with it. The 6-sec debuff from Spear Lunge makes it even stronger.
