Playing against Heimerdinger
How to counter and exploit weaknesses
Destroy his turrets first: without them, Heimerdinger deals much less damage and loses his zone control.
Don't fight in his turret zone: lure him away from his placements to fight.
Ganks are most effective against Heimer — but kill his turrets first or they'll kill you during the gank.
Champions with range who can snipe turrets (Syndra, Ziggs, Xerath) counter him well.
