Yes, excellent formation. I call this the WM, it's been very effective for me. Another great formation is the same, but the wide AMs are moved to AMC, used for attacking through the middle instead of down the flanks.
I do like the look of this "WM" formation. But what are its cons? Surely the DL DC DR is not enough? So DMC to have down arrows or not? I might have to wait til end of season to trial it out!
