Iffem, quick tip (it is).

Heimerdinger going mid is too easy of a target, he is squishy, has no escapes, and in mid lane he is easy to bring down since he can not drop a turret in 1 bush and be safe, he has to get rid of what makes him scary (his turrets) to remain safe, or spend a lot more money on wards, whereas in top lane he drops a turret in the bush in the river and is ungankable, or if nothing else, freezes the lane near his turret and sets up a turret barricade, it really shuts down aggresive pushers
