They toned down the effect that shows up when you do normal MP dodge. It's way too feint now I think, compared to everything else.
I think 1.0's was a bit ridiculous. It had an insane number of particles for even the most simple of dodges.
Not just that, it wasn't even true to Noctis' character and concept I feel. The perfect dodge we see now has the silhouette of Noctis when teleporting that they've introduced since E3 2013. They toned down the normal dodge and now the perfect dodge looks appropriate.
I haven't played 2.0 but everything I see seems better than what was there before. Even the camera (which is still pretty bad). I don't mind the MP being less important because everything just looks more fun now. It may seem easier, but I like that tradeoff.
And for the combo attacks, they should just have different button prompts instead of the same one. It makes it more engaging if you have to pay attention to what you're pressing.
