Trequartista not getting many touches

I have been having similar problems in this edition. I think that because of positional play, players will rarely roam inside zones where another player already is, therefore you loose the meaning of playing a trequartista (or any role which thrives when roaming) unless you have a hole in your formation for the TQ to fill.

For example, I have tried a 4-3-3 formation strikerless (I dropped the striker into the AMC position), the AMC (10) was an AP-s with the instruction to roam from position and move into channels, and the MCR (8) was a mezzala on attack, here is a heat map from one of the game I simulated:

you can see here that my AP-s is effectively sitting inside the left channel the whole game, he does not drop down to link up because the game prohibits him from moving during build up. 

I'm also rather sure the same happens for the RPM, in last edition you could see the RPM switch around with other team mates and actively move from one side to the other to create overload. In this edition, I am almost certain that the heat maps of the RPM and the AP-s in the midfield strata are exactly the same.

I think that the instruction "roam from position" should bypass the positional structure, otherwise you might as well get rid of it.
