Heimerdinger's Turret, too much range?

Do you mean the lasers which have always had longer range than the basic turret shots?

I feel like turrets should not be able to shoot past minions. They should do less damage, shoot faster, and maybe he should have more (if they do less damage)

Think i know the bug you mean, turrets just keep doing the shooting animation even though they could be in the bot lane while the turret is mid lane.
