User blog comment:ClariS/Why Xerath's Passive is Bad/@comment-72.29.231.5-20130319182441

I can honestly agree with your argument that Xerath's tanky passive does not serve him in ALMOST any way. Yes, I can agree that it helps in the event of a sneaky Shaco but his passive is only effective against a heavy AD team. After some major thought, I thought of something that might suit Xerath more and give him more of a place aside from a burst mage.

Enemies hit by any of Xerath's abilites are weakened arcane energy, decreasing their magic resistance for a short period. Now this passive would serve Xerath more. Not only will it make his bursting more effective, promoting meta play, but he would be a good matchup in the even of heavy AP based teammates, allowing more teamplay.

That's just my thoughts on this.
