Hey magicafe, I'm using almost the same formation on my 2nd team(2x ST instead of AMC a good amc.) w/o Token spending or anything.. 5Stars team and so far we'r doing great. 11 Wins and 1 draw out of 12 games.
most important thing lately on this team has been the training bonus. I kept 11 subs and now i'm getting 10% bonus every day while training them. found that this helps alot...
With that formation you'r 1 step away from turning it from defensive to attacking by just switching your AMC to an MC or ST.
I also think that 3-2-4-1 DL DC DR DMC DMC ML MC MC MR ST is one of the best formations you can use lately. As it covers really good in defence, noticed that most of the people are using 2 or 3 players in attacking mid so yea..
