To elaborate, the formula used to calculate a player’s catch-up cap is now:
<Number of weeks passed in the season> × 1500 - <Total amount of Conquest earned this season>
That number is then added to the weekly total cap of 1700. Note that, as of this post, Warlords Season 1 has been active for 18 weeks, which means the maximum possible catch-up cap for a player that has not earned any Conquest points this season is 28,700 Conquest.
