Definitely, as long as they don't bring back also those ridiculous baggy kits we used to see in PES 2014.They must bring Kit physics back.
Also, phisicality in PES 2014 was better than it is now (I mean, being able to keep the opponent away by simply flicking the right stick was a great addition to the gameplay mechanics even if these situations would too often result in a "deadlock" with both the players engaged in a shoulder-to-shoulder battle being unable to stop the ball from going out of the pitch no-matter-what).
Also, I'd love to have the CPU add more variety to the finishing: not every goal in football is scored with low curled shots on the far post, you know. Yet it looks so in PES 2016 (I've only played the demo and PES 2016 MyClub honestly, I don't know if in the full game it's any different).
