I think we'll roll with the current rule for now. It would only be one player per year for a total of maybe 15 players on the top end (of course they would be the better players on average). If there are enough concerns I'm okay discussing it. Maybe if enough people want to go with limiting it to a change every other year.
Forgot to mention, now that I've modified the player origin percentages there's a decent chance that not as many people will even do this every year. There should be more top prospects available from each nation that has a WBA team moving forward, certainly for those nations who've had a WBA team for a while.
