From another site:
"Corruption Will be Removed in the Shadowlands Prepatch!
Game Director Ion Hazzikostas confirmed that Corruptions will completely removed in the 9.0 Shadowlands Prepatch, while Essences and Azerite Powers will only stop working in Shadowlands content."
Now I ask you:
Is it weird that I have this huge sense of wasted time every time an expansion ends and another starts?
Do you remember your legendary BIS from Legion that you spent hours, days, weeks or months to drop ?? What are they for now?
And all the essences and azerite power that I've grind like crazy in the last few months ?? They just stop working ??
Okay ... a new expansion will arrive and we have to "disconnect" from the old theme of the last expansion .. but they simply tell us to throw our wasted time in the trash. I don't think it's fair.
There should be a way for our legendary items from other expansions, essences, azerite power, corruption and everything we spent a lot of time to get exchanged for something precious to use in the next expansion. Just my (maybe unpopular) opinion...!
