This must be the single most exciting post I've read in a while.
Glad to see that speed has been toned down a little, as PES 2017 felt too fast to me also with -2 speed at times.
Not a fan of more responsive dribbling but happy to see that the speed burts now is more useful. I've read that catch-up bug has been removed so hopefully timing the speed burts at the right moment would do a bigger difference this time.
I'm absolutely OK with shot error as far as it's also from the CPU (a thing we'll have to see with the demo I presume, and the same goes for the fouls). The occasional player getting 'stunned' for a split second (thus losing the ball or losing the chance to reach it before the opponent) is what annoys me the most of PES 2015, which I still consider superior in many areas to PE 2017. If this is fixed in PES 2018, it's a huge improvement, even bigger than the change in pace.
I don't care if the graphics haven't evolved compared to PES 2017 PS4: they surely have if we compare them to PES 2017 PC and that's a good thing. A little worried about headers and crosses but I plan to play this offline for the majority of the time so no big deal (as long as the CPU doesn't resort to them too often, but I hope to see different teams play different styles). Not worried about defending either, I hardly use the "contain" button (sorry for speaking FIFAish but that's the name I recall for that behaviour), I only use the double tap on 'A' for the standing tackle. I also hardly use the teammate contain with 'X', so...
You've really got me excited, and I haven't downloaded the beta yet. Go figure.
