Minmaxing is generally a bad idea. I can understand doing it in video games as they tend to be combat heavy and have a fixed story. But in PnP games minmaxing is boring and with a one dimensional character you are robbing yourself of so many interesting stories that could happen.
Sadly, minmaxing is easy and also can easily be discussed in reddit forums. And with the current generation having short attention span and being massively entitled to always "deserving" to succeed and be the best even the PnP games now get changed to appeal to minmaxers. The ASI change for example is one of those things as the only ones benefiting from it are minmaxers who refuse to play something that does not have the "best stats" for their class and call missing out on 5% success chance being useless.
