So when is Riot going to fix Heimerdinger?
With the new masteries he is even more toxic to a match. Ult turret can take 3 tower hits and hits just as hard as a tower. Turrets attack so fast Thunder pops any time you are in range. Missiles also trigger Thunder if you are hit. Turrets keep attacking even when he is dead.
And there are more, so it's not like the champions you can use are limited to the point where you don't own any of them.
