Heimerdinger, Mage / Support
Heimerdinger, the Revered Inventor, is a Mage and Support champion in League of Legends. Everything below comes from Riot's Data Dragon for patch 16.21.1: ability text, base stats and Riot's tips. Counters and matchups by class are worked out from that text, and each one shows its reason.
Playing as Heimerdinger
Riot's own tips
Turret placement can be a deciding factor in a battle. Against most enemies turrets are best when they can support each other, but if the enemy has a lot of area of effect damage your turrets can be destroyed quickly. Placing turrets in brush can lead to a surprise attack in your favor.
The success of Electron Storm Grenade is very important to Heimerdinger's survival. The slow and stun both are capable of keeping enemies in place long enough to punish them, but it is also the first line of defense against a surprise attack.
Spreading out Hextech Micro-Rockets leads to more reliable damage and more efficiency against multiple targets, but focusing it creates the biggest impact.
Playing against Heimerdinger
Riot's own tips
It's better to destroy all of Heimerdinger's turrets at once with the help of creeps than to fight them one at a time.
Be wary of Heimerdinger's Upgrade!!!, as he can use it to find an answer to most trouble he gets into. Once his ultimate is down, go in for the kill!
