The funny thing with the passing is there are alot of factors that affect the final pass. Things like the palyers ability, pressure in terms of opposition pressing, pressure in terms of window for pass closing, angle, distance, body position, stronger foot etc. So in some instances we might not understand why a simple pass goes awry. That said I do understand what you guys are talking about, and I agree too. Even on unassisted (0 Bars Pass Support), AI assistance or intervention kicks in intermittently, giving an inconsistant feel to the passing. It's very strange, to be honest, but contrary to what some believe to be people working around the flaws, gaining a deeper understanding of the team and the passing mechanics will greatly reduce and possibly remove the occurences of these passing issues. If you use a team like Boca, or Athletico Madrid with a good formation that you understand, and after understanding the players as well as the intricacies of the passing mechanism, then passing mishaps become almost non existant. Why almost? Simply because we are not computers, and so cannot calculate the perfect solution for every pass. All of this is applicable to 0 pass support predominantly. I am not perfect, and I am far from a professional, nor am I an expert on this game. I base this on some of the friends I play against online. Their passing ability and knowledge, in terms of passing, with no assistance would leave you flabbergasted. Using either, :x:, :R2:+:x:, :L2:+:x:, :triangle:, :R2:+:triangle: etc, in the right scenario, with the right player, off his stronger foot, at the right angle etc, will affect the success rate of the pass.
I understand what you are saying, and yes the passing is somewhat broken but I think alot of us may see an exaggerated manefestation of what we deem to be flaws, just because we fail to understand just how much is actually going on, because we don't appreciate what is required of us and the player at any given point in time.
Just my 2 cents.
