I understand the frustration that can be caused with how things go currently regarding people having 1 account top 25 in both gold and silver.
But rather than preventing the same people from finishing top 25, when editing the list of players eligible for the ladder tournament, the staff could sort the list and make so that there are 50 different players based on their rating at the end of the season. At least, it won’t penalize players who achieved to be top 25 in both servers (I mean from an economic point of view).
