I feel that is a leading question, FrazT!
No, there will need to be no changes when 8.0.2 comes out. I maight release my tactics when I'm 100% happy wit them, but until then, look for Millie's, Diaby's, Willo's 4-5-1, crazy gra's, pelle mandorff's to name but a few. None of them are 4-4-2s, which probably means they are better than my tactics, as they will offer advantages the 4-4-2 doesn't.
I won't tell you what they are, because that would invalidate the whole of TT&F, which tries to explain how to beat the engine logically and realistically. If I detailed engine weaknesses then the AI would be beaten unfairly and the joy wouldn't be so great when you finally clinch your first title.
A quick trawl through the T&T forum will give some indication of how the engine can be undone unrealistically should it be you desire to do so. It is a matter of putting two and two together from information already available. I don't want to belittle unrealistic tactics; they are creative and valuable. Creative because they find holes and exploit them. Valuable because they help those holes to be identified and patched up, which, ultimately, leads to a better engine
