Neo your wrong lol Shyvana is OP, I have run about 4 games as and against her and raped, you just need to figure her combos out is all and many other champs are item dependent, that is no excuse for a champ to be underpowered lol. And as a heads up, this week has champs that are "Must Counters" as in they suck if countered. In order to do any good in Normals or Ranked you need to know the counter to each play style/champion. As for Graves, he is a bit on the powered side with his buckshot, it stacks up too far making his early game so good, his late scales on it.
If anyone wants to add me its: victim130. I hardly play Normals and play ranked when ever I can unless its Dominion I'm in the mood for.
