Definitely. The AI is obsessed with getting you to defend. If you ever check out the 'recommended' settings it almost always sticks you in a defensive-minded 3-6-1 or 4-5-1. Live a little, Konami.
Yeah I noticed that when I was making the Amador teams, I had an idea to let the AI decide on formations for the teams only to quickly find out it was mostly 3-6-1 with the odd 4-5-1. Tested it on on a regular OF and if you try it on a really top team you do get a more attacking one but it seemed very rare.
These days, well these days it's actually bugger all as my graphics cards chose the wrong time to die(!) but usually now I go for auto on strategies and also auto-subs but not if it's a ML.
