I think the 41221 formation is alot more solid at the back, while still having a good amount of players forward when needed. Your tactic is really good, but I did notice it could be leaky at the back. Really hope this tweak goes well mate, looking forward to you releasing it after you have done some more testing? Will you keep us updated with some screenshots?
Oh one other thing, I already have selected a large pitch size in my game, is there any tweak that can be added for it to work better on a larger pitch, or even a standard size pitch?
