Experience is nothing in the midst of battle when you don't have enough ability to back it up, and Grayfia is far weaker to Durandal than people such as Vali or Bikou are, so that more than makes up for the higher experience. Penetrate bypassing time-stop? That does not make any sense. Time stop is not a defensive ability or a barrier.

I keep questioning why you bring up Albion. Whether Albion can Divide Crom is irrelevant, because Albion can't be summoned like Issei does with Ddraig. At least not currently, so until it is revealed if Vali can do something similar, then it's irrelevant to think of what Albion can or cannot do.
