Here is an idea for the developers who apparently don't play this game or understand mathematics. By allowing a team only five training games per day but also allowing that same team to be challenges an unlimited number of times, it is very difficult to maintain a fan base. And forget about trying to get in an decent training. Today, for instance, I have been challenges 18 times and counting.
While I have drawn a couple and won a couple, mostly I lose but as an away team, most teams do lose more than they win.
So therefore, if u are allowing unlimited challenges, why not reward a new training game for every successful challenge defended.
Or am I whistling into the wind?
