“It’s probably Matt Mercer’s fault.”
People don't necessarily "need" anything, they just gotta "want" it, since this is a game for fun, they can ask for options that'll make the game more enjoyable for them. If they want to be powerful or play in a hard campaign, it's completely reasonable to want the ASIs to match their class.
And I've said several times now, it's really about what the other options are.
I don't have any particular desire to roleplay one race over another; rather I build my characters for their collection of abilities, and then I figure out their personality. If the mechanics leads me to end up with a halfling or a goliath or a tortle, then I'll start to think about how their personality and decision making are influenced by their race and background.
So when I'm making a character, with no desire for a particular race, I look at what the package of abilities looks like. And it's not that the additional +1 is just the greatest thing imaginable and is absolutely necessary, it's just that there's no other package that I find as attractive. And, again, that's largely because of vHumans: racial abilities are rarely as interesting to me as feats.
