Because it did.
“Oh the game doesn’t port my toon over to a rare insta, how bad”.
It doesn’t actually mention any difference with before.
The areas are a bit wider, and the rare announcement a bit more discrete. But it’s still the same overall gameplay : grind mobs, kill boss, loot currency, buy rewards.
Sometimes you get a rare drop from the rare like the OP neck pattern or the Heirloom trinket piece.
It’s the same event except it doesn’t replace mobs in the area, so you can still do whatever it is you wanted to do in that area, which is a win. Imagine not being able to farm Cobalt rep for 2 hours because there’s a Storm there. That would suck.
Now watch as you insult me, and debate none of the points I made. Because that’s what you do.
