After the last December update, when you maxed out your victory bonus to 3x, the maximum number of victory points has initially decreased. It was 90-210-390 points (or 375 points, don’t recall for sure). It felt like a drag to grow through the rankings.
Now, it is 120 points for the lowest league, 240 for the middle league and 420 points for the top-tier league. At least, I was able to get to level 13 for the first time.
