You're doing single rolls or what? It's better to roll that 10+1 instead..........
They only stated increased drop rate, but the fact is that it's still 6% for a 5★.

I do single rolls yeah. 10+1 ones give a free roll but at the price of a ton of 3*/4*. Here I got two 5* for 5 rolls. Okay, not the one I wanted but I still save 25 FG.

And I know 5* rate is still 6%. I'm talking about the increase of the chance to get the featured 5*/6* against the others 5*/6*. In another words, if I got the wonderful 6%, what are the chance to get Poppy/Helio instead of any other 5* girls.
On all the roll I do since I started, I got a featured girl only once (and it was a 6*).
