Power Grappling and 'grappling rolls'

[Dinadon]

In response to the original post I would say it is too seldom to be worth the split. Having looked over everything to do with grappling in Basic and MA, the overlap of both effects seems large. If someone were to take one of the effects as a perk, the utility of the other would then be worth less than if it had been picked first. In other words, the other effect is worth less than a perk once you have one of them.
