Remember the good ole days...
You know, back when the tips for countering Heimerdinger told you to "focus him if his turrets are getting out of control" since killing him made his turrets stop shooting you.
It provided an interesting dynamic, where the heimer player was forced to do an intricate dance when he was ganked, trying to stay alive long enough for his turrets to do their work. His opponents had to choose whether to commit to killing him and risk being slowly pinged down into range of his burst damage.
But now, all of that has been fixed. Now Heimer players are free to push lanes without fear. Free to run forward without any thought and simply plunk down their turrets when threatened. Worst case, they trade one-for-one with an enemy strong enough to kill the donger before dying to his spawning-pool-like turrets.
I'm so glad they fixed Heimerdinger :|
