The passive change is bad cause it affect the whole game.

That's mean whenever he use his W to last hit a canon minion, he loose all resistances against his AP opponent.

And he does have strong counters that aren't played. Gragas was one of them before his rework cause the zone, now Anivia is really strong against him.
