There is none, and people call this a "good base" for future games
That brings me to another question. The 'rails' that is the underlying mechanic for passing, running + well, everything.
I always wanted them gone as the AI interference over your control is so blatant (especially this yr) through this mechanic. But maybe 'gone' isn't the solution, or possible.
eg. direction takes priority over the power bar no matter what PA, like the Ai overriding your pass to the player that's offside (not just 14, this has been around for yrs). Tap the pass button and it'll fly 50yrds like a bullet, or fill the long pass bar full + it'll go to the guy 5yrds away
AI completely controlling your sprint speed + direction - how many times does your player slow to a crawl near the touchline to let the ball go out? How many times does the AI move your player off the line of a pass so it can be intercepted? A long sprint for a loose ball is predetermined from the very beginning
Players locking onto passes or loose balls messing up - supercancel screws this up a lot, and then there's times when you can't even change a selected player.
I put these kind of things down to the 'rails', and feel so prehistoric. Probably why I don't feel much difference between a Pirlo long pass and Brasileirao bench player

Problem is imo, every bit of gameplay code flows through these AI chosen paths.
It's an easy way to hinder your play rather than use better AI to out play you
Obviously Konami aren't gonna get rid of them, so maybe they could make them much less rigid, linear + scripted. Loosen the player movement up. So much so, that it'll give the illusion that there's more freedom.
Imagine sprinting after a loose ball were you could change direction or give up on it without using supercancel
If these same strict, rigid rails show up on PS4, X1 or PC next yr, Pes15 will feel far from a NG experience for me.
