For me the second biggest issue with the Leaf after the range is the long charge times.
6.6 kWh is better but not future proof. A 6.6 kWh charger is 15 years + out of date. We really need to have more powerful J1772 chargers being installed as well...
I hate waiting for charging too... (Thank goodness we are starting to get some CHAdeMO in my area to solve that.)
For J1772, I see some reasons why above 6.6kW may NOT make sense (even though I would like having it):
#1: Extra cost of the higher capacity charger in the car. (Do you really want to pay more for the LEAF?)
#2: Extra weight of the higher capacity charger in the car. (Weight hurts performance, range, etc.)
#3: Extra cost for the site installing the higher capability EVSE. Fatter wiring, more expensive J1772 plugs, more expensive breakers, possibly need to upgrade service with the power companies, etc.
#4: Power company concerns about the load on the grid.
6.6kW can give a meaningful amount of charge if you leave your car for a while (such as during the workday, while watching a movie, even eating dinner, etc.)
But, yeah, it sucks to have only 3.3kW or even 6.6kW if you are sitting there waiting for your car to get more range. For LEAF, CHAdeMO is the primary answer, and J1772 is just the "plan B".
I will be glad to get 6.6kW and not lament lack of 10kW because:
#1: I will have saved money compared to a higher current charger.
#2: I won't worry about carrying around too much charger weight in my car.
#3: I will feel like I am making good use of all the public 30A 6.6kW J1772s being deployed all over. (Higher currents are really the exception these days.)
#4: I will be able to make use of the 30A EVSE at my house. (My panel only had spare capacity for a 40A breaker, so I wouldn't be able to do higher rate charging even if the car offered it.)
