User blog comment:ClariS/Why Xerath's Passive is Bad/@comment-1445357-20130317022745/@comment-99.55.245.182-20130317155537

Exactly this. While I know this post wasn't about Alistar, he's a pusher. He hits the turrets. He's not a pure tank that is just there to soak damage. He's a pusher, a damage dealer, a general annoyance to face, and most of all- he takes down turrets. His high AD, an AD steroid AND damage reduction, and an AoE passive that can deal damage to turrets prove the point that he is meant for takedowns of turrets.
