Not really a problem for a small helicopter remaining at low altitudes, but definitely so for something larger, a utility aircraft or an aeromedical/ SAR one.
This may be true, but if total powertrain and battery weight is less than standard ICE engine and full fuel weight, then it evens itself out.
The gearbox will be a lot lighter and less complex if the TR is electric.
I too would expect fossil fuel aircraft to hold their place quite well in the utility and heavy load roles. I don't think that's the target though.
