Blizzard has posted a warning that the end of Legion PvP Season 7 is coming soon. In the gap between the end of Legion and start of BFA PvP, there will be a special post-season allowing players to get catch-up gear from strongboxes.

This also serves as a reminder that the Battle for Azeroth pre-expansion patch is coming soon--however, no date has been given yet. Usually end-of-season warnings are given 2 weeks before the season ends, so with that logic, the Battle for Azeroth pre-expansion patch could go live on July 17th.So you can buy the 1800/2000/2200 Rating of S6 with cheapest price on team4power.com.You can buy cheap wow item&gold and raid run with all loot also.

The gates will soon close on Legion PvP Season 7 with the release of the Battle for Azeroth pre-expansion patch. Don’t worry though, you’ll still be able to take part competitive PvP in a special post-season which will end with the launch of the expansion on August 14.
If you participated in Season 7, 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 Legion Season 7 has ended.
Legion Season 7 titles and mounts will be awarded approximately two weeks after the season ends.
Faction-Based Rewards
Don’t forget—end-of-season rewards are based on your faction. If you transfer your character to the other faction, you must have 50 wins after your transfer to receive the reward and 150 wins after your transfer to earn Gladiator and Dominant Gladiator.
Jump into Post-Season
Once the pre-expansion patch is live, we’ll be kicking off a special post-season through to the launch of Battle for Azeroth. While there will not be any end-of-season rewards such a mount, title, or Conquest to earn, players will be able to gain catch-up gear that will be rewarded from strongboxes.
Leaderboards Temporarily Offline
Please note that PvP Leaderboards will not be available once the pre-expansion patch goes live but will become available again with the start of the new Battle for Azeroth PvP season.
