Yeah, but why first-off are you bothering to look at other people's character sheets... and on top of that, a modifier only one or two points lower than a supposed "non-boring" stat array does not actually show up during gameplay as anything appreciably different. So it's nothing more than just arbitrarily "thinking" that an 8 in some stat all the time is some big issue. But in actual gameplay at the table it is pretty much meaningless.The "boring" is when the same stats keep getting that 8 every single time. The frequency of 8 in Str, Int, and Cha feels like poor design to some of us, and making some targeted improvements may lead to more diverse character options.
Just stop worrying about other people's character sheets and instead watch players just play at the table. Cause then all the supposed issues just disappear.
