Special note: The two Darkshore changes will only take effect after the current Warfront cycle has ended. So if Alliance is attacking Darkshore in a given region when Season 2 begins, and has 3 days left in that attack cycle, that Darkshore will still give Season 1 rewards. ◦This is being done to avoid any unfairness to people who had already completed the Warfront or done the world boss just prior to the season rollover.
Mythic+ rewards will also go up by 30 item levels; however, during the first week of Season 2, rewards from end-of-run chests will be capped at Mythic 6 quality (item level 385), and the chest you open next week will contain Season 1 rewards if you do a Mythic+ run this week. (So, for example, if you do a Mythic 10 during the final week of Season 1, you’ll get a Season 1 item level 380 piece and 60 Residuum from your first Season 2 chest.)
