I've played this formation without that many arrows for quite q while but found it too vulnerable for my liking. Especially with red arrows on the ML/R. I think btw you can be succesfull with (m)any formation(s) if you got the players that like to play it. Having said that, being the skeptic that I am , the pics dont say much without the players Q posted. The one post that does have it shows a more realistic picture, that you had a (much?) stronger squad.

I'm not saying it's a bad formation, not at all, but I'm not conviced it's any better or worse then some other formations by what's shown in this thread so far.
