I don't see any problem with that. Individuality imo has never been that good and there's no catch up bug or anything like that.
It all depende on cicunstance.
If C. Ronaldo is on the run and recieves a perfect grounded through pass and he just need to sprint on a straight line or make just minimalista body adjustments, absolutetly no one can catch him. But if he's sprinting with the ball in a far wide position and you want him to cut in side to be in a proper angle to shoot at goal, he will naturally make heavier body adjustments (unlike in Fifa in wich he literally fly while sprinting when turning in every angle) like any normal athlete (i know he's a special athlete tho), wich could give minor seconds for defender not much far from him to come soon enough to close the angle and eventually block the shot, specially if the defender sprint diagonally.
Body adjustment and angle matter a lot on This game and thats a very good thing, it creats balance and realism to the gameplay, wich for me it represents a fundamental advantage of pes this year over any Fifa.
Last years game had an absurd Issue with catch up bug wich was a joke, slow defenders always got a misterious boast and became usais bolts in a split of a Second, but thats not the case with pes 2015. In pes 2015 fast players can easily outrun slowers one, specially on a straight line, but body adjustment and angle are very relevante wich is a good thing as I said.
