Misses are sometimes frustrating. Attrition is always boring.
Take your pick.
Soo, of those 12 missses, only a few are frustrating, some of them are 'meh' and few are 'hey this is pretty damn cool'. No seriously, how does that make any sense.
And some please explain how grazes lead to attriton, to me
makes perfect sense.
Replacing grazes with misses makes combat even longer. Instead of some damage you deal no damage.
Replacing grazes with another similarly balanced system, will by definition, result in the same lengths of battles.
Grazes don't make combat longer in and of themselves. "Combat takes too long" (which I assume is what people mean by 'attrition', honestly I don't know) is a largely independent problem and can also be solved by reducing enemies' HP.
So, yeah, I don't get the argument.
