I don't think Raven overdid it. You all attacked an unprovoked Navi with no questions about anything, and didn't even bother to find out how powerful he is. It backfired and now you're all dead. Think things through next time. Good doesn't always conquer all.
Well, element-wise it makes perfect sence, but not goin' into that.
Look, I'm going to be blunt; Eon has ALOT of other skills and strategys, making him in essence invulnerable at this point.... so for the sake of moving the story along, we're going to say Eon wins and move on.
