In my experience they largely pick decent teams, BUT there are a few glaring examples of terrible AI. I posted a screenshot earlier in the thread that shows Liverpool have played Salah just three times all season (over half-way through now) - he's not been injured. They've just played poor replacements (and kids) instead. So much so that they're in the bottom five...
However, you can put a controller over to the AI side and "correct" their line-up pre-kick-off should you wish to (which also lets you see the formation they're using, so that you can prepare tactically - without doing so, you've no idea what formation they use)...
Oh yes it was your post that I read. It kills it for me Chris because I am a bit of a stat man and I love looking at how many goals, and by whom, the other teams are scoring. I know you can change the line up for your game but not for CPU v CPU.
With me playing all the EPL games I can also change the lineup for each team. But yep obviously this is going to take me months to get through a season. But I am hoping that the individual games can give me the enjoyment I want and not so much the overall experience over a few seasons of CM.
The only thing that annoys me is that the player stats only include Goals, Assists, Clean Sheets, Yellows, and Reds. I am sure that there was a FIFA when you could see each teams injuries too. There have been a few niggly injuries so far and I would love to be able to see a page that shows how long they are out for. It just adds to my imagination and the whole immersion thing.
