No offense but this isn't hidden information. And in reality it has far more uses than just being an escape. It makes Ahri more mobile in general she can close gaps for kills easier, duck in and out of team fights when she see fit, give her self a better angle for landing her skill shots. Not to mention the fact it deals damage and allows her to proc her passive more often to increase survivabilty. The information you gave is basically reading the tool tip for Ahri's ult. Not really much of a tip or trick.
I know, I was simply talking about it's other uses if you want to use it to escape rather than deal damage at the time and wait for the cooldown.
