Last year I tried using mostly generic playbooks and the results were less than stellar. The playcalling tended to be too pass oriented. This year, the generic books, except for Run Heavy all have the pistol and wildcat formations. Those two kill the immersion factor for me. That is I have gone to the Ravens and Colts playbooks this year. While they call too many shotgun plays, the run/pass ratio is better both in game and in simmed games.
I am open to trying anything though.
I am getting more and more frustrated with M18. I really like it at first, but since the last update the pancake blocks are out of control. I cannot use my 2nd controller process in Play Now games without the game crashing.
There are certainly some things I like, but the bad is starting to get really annoying.
If you set up the generic play books and stamina like you are talking about, let me know how things work for you. I am always interested in picking up new info.
