I've run a game as Burton Albion for a while and you may as well take your nuts and slam them in a desk drawer for all the enjoyment you'll get from it. Some teams you can muddle through against, but too many League 2 teams seem to have signed the entire Barca 1st team squad given the crispness of the passing and quality of the shooting you have to deal with.
I also placed Bayern in the Scottish 3rd division to test formations, and while we won most games, too often we won by 2-1 or 3-1. We were also in Europe through Germany, and we sailed through the CL, including a 6-0 beating of Feyenoord. I think playing any teams sees oppositions play at a level not based on the ratings of the players.
Mind you, every thread I comment in sees Mike shut it down a day later.
