Forget to mention another thing. It's about setting easy tackling.
I believe this thing is useless, no one use this mode. But how about to use this mode for friendly games ?
When we want to play a friendly game and set to easy tackling, not only our team but opponent (friend's) team 'll also play in that mode. So we cannot have any injury from a tackle (but from other factors as low morale or condition).
Easy tackling can reduce the defense ability of our team by a 5% but doesn't matter because we chose an easier friend to play anyway
