Deal breaker is much.I agree. And I dislike fighting styles so much it's pretty much a deal-breaker for me running 5E.
I loathe design that forces characters into one-trick pony silos. Fighting styles compound that problem of being limiting by also being boring. And, in some cases, like great weapon fighting, actually annoying ("oh wait, Bob has to roll his greatsword damage again....").
Its easy to alter fighting style to making them not solo and more generalist.
Outside of DNDBeyond, its minor and fixable.
