I understand it´s not a major issue. But i think it could be a realism improvement quite easy to program. I guess developers are working on more difficult problems but it could be an easy way to give something new in the game. It´s all about changing some values.
Some managers will obviosly whine, but it will avoid some managers to have always a filled arena just winning their away games. It´s an awful game design, as day trading was, that must be changed.
