I presume this is responding to me. My statement did allow some of the irritation of perplexity to come through but I don't want that to take over its content.
My point is not that diversity is bad, it's that the recipe sites I have looked at are not diverse, they're rather consistent with are IMO strong mixes, and the advice here is often lacking much between similar flavor levels and the unflavored advocates. The difference is not small, either. Certainly someone who has sensitivity problems should look into trying unflavored and subtle mixes. I can tell you that this is no disadvantage and it can be awesome to vape teasing flavors mixing with the flavor of the eliquid base. This calls for flavoring levels often below 1%. The lowest I have used is .02%. It's easy too, when using only a few drops of flavoring.
One thing you can try is simple dilution of eliquids with unflavored, e.g. 10-20%. If mixed and allowed to steep, the flavor becomes stronger. The flavors may not be ideal, admittedly my DIY flavor combinations would probably be harsh at full level, they certainly are to me. I keep dropping level. I also do make at least one higher strength juice, but for low power tight MTL only. It is excellent but only in that kind of setup.
