the abuse the poor keyboard suffers as a result
Has anyone here actually experienced the "wearing out" of a keyboard key in this fashion? I tend to class such statements alongside other folk legends like "if you keep making that face it will stick that way".

Regarding rapid-button-mashing QTEs though, yes, I think I would hate them; I can't remember the last time I played a PC game that required it, though (aside from odd little Flash games).
