I don't mind QTE's..the only QTE I can't stand worth hell is those in cutscenes, and if you don't get it right you lose.
For example: Far Cry 3 hoyt fight, GOW QTE (although those make you feel good when you do something badass) Halo 4 QTE (did NOT need them at all) and CoD QTE.
I don't think that DmC's platforming is QTE, it's just simply what it is: Platforming.
If DmC's platforming is QTE, then the little parts of DMC4's platforming (well..I don't think the word for it is platforming) but just when you're Nero and in the torture room trying to get across without hitting the spikes on the ceiling is QTE as well.
To me, QTE's are those which penalize you with the death penalty, making you go back to the long loading screen just to fail it again. While, DmC's "QTE" just puts you back up to the beginning with no long timing or having to do the same things before.
Sorry if I'm not making sense, I'm tired. and please know this is my opinion on QTE.
