I don't think it can be as in B, since capping the percentage would mean a different end value for different cap for cards with different values. But you'll get the same caps for a GSR as a GUR.

Don't think it's the number of buffs to stack either, since a similar problem would arise again. It should be just a flat number that your end ATK or DEF can be.

I think your DEF is maxed at the same amount that your ATK will be maxed. I've used 200% or 250% buffs only in LAW battles and 3-4 procs seem to do the trick. Depending on the RNG and the element, LAW should be hitting for 1700-2200 dmg per hit with max DEF and no debuff on LAW.
