Recently switched to a 4-2-3-1 in this style

-------st-------
Aml---amc----amr
---------------------
---dmc---dmc----
DL--dc--dc--dr

It's been successful as I climbed from 11th in the table to 6th rather quickly vs all kinds of formations

I use defensive,focusing passing down the flanks, mixed passing, and force counter attacks.

Should I use long passing since I have such a gap between dmc's and amc's?
