I agree with the too much flavor and Ill bet there's others on the ECF like me. I think its a remnant of our smoking days. When you buy a flavored cigarette, like menthol, most of them are slightly flavored on top of the tobacco taste.
It actually saves me some money. When I buy a bottle of juice, I usually buy it at double the NIC level as I want, then I mix it 50/50 with straight VG. It lowers the NIC to where I want it and tones down the flavor. This works really well with some juices, but your mileage may vary. It saves money because the straight VG is dirt cheap and you double the amount of the juice you bought
