You're right, to a point. I'm not trying to be argumentative, but there are big fancy builds with lots and lots of wire in them that meter low but are huge coils. Fantastic flavor that you can't replicate by building a higher ohm coil. I've been trying. A zipper, any of the claptons, tiger wire, et al are all examples of high mass, low resistance builds that are astounding flavor (and correspondingly, vapor) producing machines. Is it necessary? Not even a little bit. Can that be your preference? Yeah.
If you like a huge airy draw and you still want a high degree of flavor, you have to do a large, fancy, low-res build. The only time that option is incorrect is when safety is compromised.
Having said all that, I like a .8 26 gauge build in my Subtank mini RBA section as much as I like a big honkin' dual clapton at .2 in my freakshow. Vaper's preferences are very personal and it's a long journey of trial and error to get where you even find your preferences let alone to be able to replicate them.
On-topic: That behavior is normal. Regulated boxes are voltage converters with an expensive ohm's law calculator in them. (Gross over-simplification, I know.)
