Single rolls (are supposed to) have the benefit of stopping when you pull something good. Then again, I went a full 25 rolls before I got Lilac (a silver) during her spotlight.

Bottom line, plan out how much you want to roll, because the 11th roll generally doesn't make a huge difference in the end.

Statistically in the long run 10+1 should always be better though. More rolls equals better odds in the long run. As someone who got 1 gold out of 5 10+1 pulls I wonder though..

Just bad luck, you can get more than 1 as well :P

Look at her name and you will understand why ! The legend is here !

Btw, doesn't matter how you roll the gacha, the drop rate is still the same, it's all about luck. I saved up enough gems through 3 events to make 2 11x rolls, 1st roll was 6 silvers and 4 bronzes, and this was the 2nd roll

We're talking LOTS of 10+1 and not just a couple of rolls. That 11th roll still falls under the same rules as the single rolls, with the exception of it being a "free" roll. However, since you can't statistically evaluate a roll in fractions, then in order for the 11th roll to pay off as a whole, would require significant amount of 10+1 rolls.

In short, you're more than likely to roll a gold at current rates in any single roll, than see that "free" roll pay off. Unless Nutaku tweaks the chances on a 10+1 roll so that on average it works out to be a few % higher chance than a single roll.

Edit:

Put it in another way. You have just as many chances to roll 2 stars on a 10+1 compared with a single roll. People posting salts about 10+1 "miracle" rolls don't hear from people who also pulled singly and obtained 2-5 in a row miracles. Why? Because it's much harder to prove those kinds of screen captures and no one would bother to video cap each attempt.

It's still all up to luck though, and that free roll could be the lucky roll and it could not be. Why waste a free roll anyways? :P

That's literally the entire point of my argument.

If, say, you're just aiming for that one gold/rainbow, you don't want to think long term, you want to roll the minimum and stop when you get it. If you want to maximize your rolls, go for the x11, but if 100 single rolls don't yield any promising results, it's not necessarily the case that ten x11 rolls will make a difference besides having ten free rolls.

All I know is that I got Cattleya off of a single roll. When everyone was posting God x11 rolls I rolled another few singles and got Chocolate Cosmos. Saving up for the extra roll makes sense, but I prefer not feeling locked away from my gems when I have less than 50. That and being a lucky asshole I'm kinda biased toward single rolls.
