Is it really that difficult to obtain? I had the fragment skill on for my crystals and got Omega on my first attempt. Haven't been able to get Lightning or Amador yet.
I tought you could get only Lightning from that fight, and it took me the whole weekend to get her, I fought Omega 3 times yesterday, no luck, do I have to 5 star him? cause the most I get are 3 stars currently, need a better weapon for Serah :-/
As for the Skins, I was expecting the worst, but Serah looks MUCH better than her default skin, have you looked her up close?, it looks so stupid, and poor Noel, ALL of his skins look TERRIBLE, I have high hopes for his AC costume tho.
