Playing against Heimerdinger

How to counter and exploit weaknesses

1

Destroy his turrets first: without them, Heimerdinger deals much less damage and loses his zone control.

2

Don't fight in his turret zone: lure him away from his placements to fight.

3

Ganks are most effective against Heimer — but kill his turrets first or they'll kill you during the gank.

4

Champions with range who can snipe turrets (Syndra, Ziggs, Xerath) counter him well.
