Did all I could (for my voting score!), but it doesn't seem just being associated with Ike is enough to carry Soren to victory... except by sheer fluke! GYAHAHAHA! I actually got both in the top 1000 (ranked 999!) and the army victory at once! (Yeah, sure, 3000 feathers ain't what it used to be, but it's nice to finally get in the top bracket for once.)
Amusingly, I often actually did get Ike popping in as the "friend" slot ally, ripping enemy teams apart.
