I'd also like to hear an explanation for the difference in the defense boost for Gallant's vs the attack boost for Chaos. A given amount of attack is -always- better than that same amount of defense, yet Chaos's percentages are about 30%-50% higher than Gallant's.

Lucky Chaos is +25% attack; lucky Gallant's is +15% defense
11 Chaos is +31% attack; 11 Gallant's is +20% defense
etc.

Both get a +10% bonus for job in party.

If we're going to get a defense boost, why is it not at least on par with the corresponding attack boost roll?
