What is AGGRO, why is it any good...

[MythTrip]

I assume a higher AGGRO means enemies will more likely attack the character. Is that rightr? What good is that, seems uselles. How would I use it in a battle?

+AGGRO draws enemies. This is good for *certain* units w/ high ARM and/or dmg-absorbing abilities. Lures enemies to attack, which can be used strategically.

-AGGRO repels enemies. Good for fragile heroes you don't want harmed. As the AI "weights" are not so clear, don't rely too much on that!
