I don't know, the two combat system aside from targetable parts seems much different to me. Dd is much more fluid and satisfying. Also the mounting gives you control and it's not a glorified QTE like in mh
I'd say it's up to anyone's taste. Something like DD would satisfy anyone who's looking for more fluid and relatively precise combat, but to me there's something about MH's pre-hunt preparation and stuff that made it intriguing to play in general, giving something entirely different than what I experienced (and loved) from DD.
Anyway, which part of MH has glorified QTE? To be perfectly honest, though, I haven't really played MH:W. I'm speaking from my experience of playing old PSP MH games (and this is many years ago, too), and what part of MH:W I've 'experienced' were those from watching my little brothers playing the game.
