I have always ordered the flavor shots, and they are just about right. I think that without them, they might be a bit subtle for my own tastes.
I also switch around atomizers for specific flavors. Though, ones like my derringer, goblin mini, and serpent mini seem to consistently provide excellent flavor across the board (as long as I have the right build in them of course).
Its tough to relate anything to other people on this topic. We not only have the impacts of equipment and builds, but personal preferences as well. Flavor is really my only concern though, and I have been extremely satisfied with V3. Fresh out of the box though? Nope! At least not for many of them.
