From what I've read today (so never tried it myself) it's all about wicking and surface area and temperature:
High wattage for lower resistance ohm vaping is using thicker wires who have lower resistances and using more coil wraps in rebuildables. So the actual surface area is larger, and surface temperature is lower and more spread out. So a larger area evaporates more liquid, and the hot area isn't just at one small area.
Wicking plays an important role, since evaporating cools the coil and avoids burning, so as soon as liquid stops the temperature jumps up. Dual coils are also meant to increase the total surface area. Another thing you can do to increase wicking is using less thick liquids e.g more PG than VG and specific aromas. Air flow also plays a role for wicking, the thighter the draw (small hole) the more suction you create that increases the drawing in of eliquid from the tank instead of the air hole. Burning isn't good since it can create other chemical products. I think the best thing you can do safely is to increase your wicking, maybe by replacing the silicone wicks with cotton. Or maybe drilling another hole into the atty casing? But haven't done that either. But from what I've seen, the mass manufactured wicking can easily be improved upon if you do it yourself.
For normal atomizers (I'm gonna try the 1.6 ohm dual coil atty for nautilus next) you don't need that high wattage. Sub ohm and high wattage is why many use mechanical mods because everything is only dependent on the battery then, but it is dangerous if you don't know
exactly what you are doing.
What I am wondering is why nobody build some kind of alternative heat spreader atomizer that spreads the heat over a larger surface area so you don't have to waste so much ampere on low resistance coils.
Or why there isn't a manufactured atty that uses thicker wire but really long and many many coils to increase the resistance again, but spread the heat over a larger surface area. Basically something like a dual / triple / quad coils that are connected in series instead of parallel. Or is that what the dual coil attys for the nautilus and aerotank do?
PS: Please correct me if I got anything wrong
