User blog comment:StrategicMagic/Xerath and AD Mids/@comment-5933544-20130102234117

He may be better than many other champions in facing off against AD Casters, but...

1) He has no escapes. Once he gets jumped on, only option is to flash out.

2) His E-Q stun combo relies on his Q, a skill shot to hit. Many AD Casters are pretty mobile and unless shot from point-blank range, from fog of war or clutch timing, skill shots generally can easily be dodged.

3) Yes, he may get passive armor with AP investments, but he only gets 15%. You hardly even have 50 AP without runes in the early stages of the lane phase.

There is a reason why Xerath is one of the most underused champions.

Play Ryze to counter AD Mids with AP Mids. He is probably the one and only AP champion who can trade even/better vs AD Casters. Just build Chain Vest + 2 Cloth Armors (Later into Frozen Heart).
