Sure. And I bet some people still cook by rubbing two sticks together too. Nothing wrong with that if it works for you. But other more intelligent people already knows about harm reduction. They know at the higher the vape temperatures, the more likely the vapor becomes dangerous. And by throttling the max temperature, you are reducing the possibility of harm. For some this is important and for others, they could give a rat's ass.
Ever heard of the term 'Ad hominem'? You're continuously grossly over-exaggerating the downsides of wattage rather than actually describing the benefits of TC. Doesn't make for a very good commentary.
To continue your metaphor, do you use an infrared BBQ? They're great, there's no denying that, but if I can cook a mean steak using charcoal, why the hell should I spend $1000+ to replace my grill just to learn how to cook that steak to perfection again? It should be easier, it should be better, but if I'm well satisfied, what is the point?
Long ago I read a story about a fisherman in Mexico. The guy would go out fishing every day to catch his dinner and sell off the excess. When tourists were in town he'd take them out to make a little extra money. One day he takes out this businessman, the man so impressed with the knowledge of the fisherman suggests he builds his business. He could hire another boat and teach that captain his tricks, this way he could catch more fish and bring in more income through tours. The fisherman asks "then what" "well you buy another boat and another boat until you have a whole fleet of boats working for you", the man asks again "and then what?" "well you can then retire and do what you enjoy for leisure, you can go fishing every day and enjoy yourself, catch what you want and have a nice dinner." Point is, the businessman failed to realize that the fisherman was already living the dream retired life that he sought. Why jump through a ton of hoops just to get where you already are?
And, that's what we're talking about here. If someone wanted to take 8s pulls and were encountering issues of either overheating/burns towards the end, or an unpleasant ramp up time, then of course TC could very well help. But, the OP is enjoying their vape, has no complaints, and is asking what TC can do for him, and quite frankly, the answer is 'nothing,' TC can lower ramp up time, it can prevent overheating, but that's what it does, it's not some miracle to make your vape hands down better, it just adds more controls to tweak. I have nothing against TC, it certainly has it's benefits, but I'm like the OP in that I have been able to dial in my vape to make it perfect as far as I'm concerned.
As a quick aside, my spell check wants me to change the word "hominem" to "Eminem" apparently it likes rappers more than Latin terms.
