Yeah, 'Offense' or 'Damage' would be alright.
It's mostly a point of fine semantics, but currently it's Attack/Defense (which pair logically... but they define damage, not accuracy) and Accuracy/Dodge.
Somewhat related, they need to show Spell Mastery/Spell Resist % chances of success in a tooltip in battle when casting resistable spells.
... come to think of it, the Critical Chance doesn't show a % value at all, so I have no idea how valuable the +crit trait is.
