Not hard to find man lol.Battle for Azeroth PvP Season 4 Ends and the Post-Season Begins
The gates will soon close on Battle for Azeroth PvP Season 4 with the release of the Shadowlands pre-expansion patch. Don’t worry though, you’ll still be able to take part in competitive PvP in a special post-season, which will end with the launch of the expansion. The new Shadowlands Season 1 will then go live shortly after the launch of Shadowlands.
If you participated in Season 4, to ensure you receive the rewards that you’re due, please keep the following in mind:
Refrain from transferring your character(s) to another realm or faction until after Battle for Azeroth Season 4 has ended.
Battle for Azeroth Season 4 titles and mounts will be awarded approximately two weeks after the season ends.
