It's more complicated than that. The only time you need more power on lower resistance is if the coil is wound using high gauge wire (28, 26, or 24). This is because the coils takes longer to heat up due to the mass of the wire, so more power is needed initially to get it up to temp in a reasonable time frame. However after that initial burst of power you are still better off running at a reasonable wattage. That's why most of the new devices have pre-heat where they ramp up the power for the first second or so and then drop down to a lower wattage.
I've been vaping since 2009. I'm only 36 yrs old, but in the vape world I constantly feel like an OG. I still wind my rebuildables using 30g kanthal 2mm 1.5 ohms and run them at 8 to 12 watts. I find that it gives me longer battery life and a darn near instant coil heat up. Now all you darn cloud chasers get off my lawn.
the whole point of low resistance is more power. looks like youve been vaping about as long as i have. remember when they first released the LR 510 attys? it certainly wasnt to use less power. it was to put out more watts at the voltages we were using. The point of a low resistance build has always been to get more wattage with less voltage. you throw a 1.5 ohm coil on a vv device that can output a max of 6 volts, you have a max of 24 watts. you slap a .5 ohm coil on there your max is 72.
