Thank you for showing us the website, friend. Here I find the true last official hotfix from that ability in bfa:
“Mistweaver Monk Rising Mist Hotfix for April 28th”
https://www.wowhead.com/news/mistwea...il-28th-312291
Let's quote from the website: “Rising Sun Kick...extends those effects by 4 sec, up to 100% of their original duration.”
Which means, to be working blizzlike, a mistweaver monk, for example me, who have 15% haste, with the help of Thunder Focus Tea, can extend Enveloping Mist to 100% of its original duration easily.
But since the effect is cut down to 2 sec (which hotfix was canceled within 1 week in official server), to extend the duration of Enveloping Mist by 100%, I have to stack my haste to 150%! Even with the help of Thunder Focus Tea! So does it work blizzlike? I don't think so!
To have a blizzlike and meaningful talent choice, the effect Rising Mist should get back to 4 sec.
