I personally don't mind QTE's. It can be fun now and then. And I kinda like if you can go down different paths in Story Mode and unlock different outcomes. It gives the Story Mode some replay value, trying to unlock each path and such, to see what happens if you do things differently.
What I don't like is if the QTE's and the different paths are unlocked per chance. Like, if you do good on a QTE, you unlock one thing, but if you suck at it, you unlock another. That would suck, imo. My reactive reflexes aren't all that great (one if the reasons I suck at playing online), so if I need to hit a button perfectly 10 times in a row to unlock a certain path, I'd have to make several attempts before I might get it.
So hopefully, it won't come to that.
