We've hotfixed a bug that was inflating the Trophies needed to increase the trophies needed to progress the PVP reward track. While progress percentage should remain similar, the fix has unfortunately resulted in a small squish of total Trophies.
We still anticipate the ability to complete the reward track with high-levels of play in the time remaining in the season, but will be monitoring point distribution across servers and considering an additional adjustment before season end.
