The patch date has not been announced but it's expected it may go live sometime in April. Evidently this is the biggest patch Blizz has ever done. Be prepared!
Sime quick take-aways:
(1) spend your AP before the patch - it can only be vendored after the patch.
(2) save your rep tokens - we will have to progress beyond exaulted.
(3) Tomb of Sargeras will not be introduced in 7.2. It will come later.
(4) Finish your Broken Isle quests so you will be prepared for the next batch in 7.2. This leads to flying. It will be acct-wide.
(5() Sell your obliterum and the braces needed for the quest BEFORE the patch. There will no longer be a quest to get the obliterum forge.
(6) Sell your excess herbs and ore BEFORE many get flying. The price should drop drastically once we can fly to the nodes.
(7) Stockpile your order resources. You'll need 60k.
