Some people choose to make characters instead of builds. Some of the people who only see things in terms of builds don't even know what my first sentence means.
Agree, many of us just play a certain class and race combo not even thinking about if it's good or not, we just want to play that.
I don't think that a +1 or +2 bonus is a big game changer, you will still be able to play whatever you choose to.
Don't get me wrong, I min/max to a certain extent, even though I consider myself primarily a roleplayer. But only within a given character concept. The fact is, none of the D&D video games are hard enough that you are forced to make optimal builds in order to win. And that also goes for all the official D&D tabletop adventure modules. A good DM will tailor encounter difficulty to the strength of their players' party, so in most cases, even in tabletop D&D you don't really need to make optimal builds either.
So if you wanna be a halfling fighter two-handing a battleaxe, with extra Int because you want him to be good at History checks, go ahead. You're still gonna be able to finish the adventure.
