Everyone was weakened except Goku, Broly and Cell. Hell Gohan was half powered and couldn't use an arm and he overpowered someone more than twice his power. I'm just saying Goku could help close that weakness, especially when all 3 are unleashing their limits. Gohan should still have the potential, a pissed of Goku protecting his family definitely gets a raise, and Goten is useless but gets something.
Which is why I'm saying that even if Gohan from half power got up to a 3 times boost which would put his power above Cell's by a lot, they should be able to match that even without factoring in limit breakers. Cell's own power also got blasted back into him as well which would help disintegrate him. All Gohan really has to be is a decent degree above Cell and all that power including Cell's own power should do the rest.
It becomes messier than it should assuming blast levels. Which is why it'd be more reasonable to look at the context of what happened between the beam struggles as opposed to assuming one is way above the other. I personally think the family one is above the father son, you think the opposite. Not getting anywhere.
If you assume the blasts to be of equal power, do Broly or Cell come off looking better in this case? That was my original point or where I was going.
