Oh I realize he was writing about PE but the part I was referring to, in his quote, wasn't about that talent, it was just about pvp damage in general, that's why I bolded it .
I'm just going off what the guide said, and it said its damage contribution was lower along with making the rotation more complicated. I don't want to buff the talent I'm just trying to argue for a buff to lightning bolt to make the talent more viable, and mostly because I frankly think it(lb) should hit harder in pvp. However, the problem is just as Blitond and you have noted, even if the damage contribution is on par, the talent still might not be picked. I'm not even sure its higher skill cap really, I think the talent is just perhaps flawed.
