I agree

If oppo has DMC or DML-R play mix,
because many lines of oppo squad (attackers- midf. players - DMs) make long pass more difficult to work,
If he isn't using DM, set long pass.
But be careful with the comments of assistant.
If he mention that oppo cuts out pass, switch to mix
I wrote about that here #6

Presence of a DMC reduces the effect of counter attacks with long pass even if opponent doesn't have AMC, only AML-AMR.
Also if oppo doesn't have DMC, it's worthy to try long pass (but must be careful).
