I'm using 4-5-1v. But when I face the team that don't have DMC I will put AMC to my formation. Here are the question

1. When I put AMC do i have to bring down my AML/AMR to ML/MR or can I use AML/AMC/AMR together ?

2. My 4-5-1v always use normal, down both flank passing mix with counter attack. If I want to put AMC do I have to change my orders ?

3. Is there any effect if I put the player in to the position that they're not familiar with ? (for example I put my MC up to AMC)

thx for the advice
