I worship free tickets right now. I dunno if my luck's turning to EX, or they secretly fixed Gacha rates.
Yesterday I got my 7-day Ticket, I used it and get the Rin CE, which I still think it's worth the 5-stars it can do as opposed to like, the Nero CE.

Then logged-in today, get the 2 free tickets from the log-in, and at first I was thinking twice if I should use it, since I already got the CE I want yesterday. So decided to give it a go, and poof. I got this after using the very first ticket. After that, I decided not to use the other ticket, because I'm pretty sure I used up all my luck.

Also, apparently that's how her sprite looks like. I expected it like, facing back-to-back or something.
Edit: Oh, and it looks like people have been finishing the Okeanos chapter fast to get Medea Lily. Some people have already summoned her, and everyone's going wild. If anyone plans to get her btw, she does not have a rate-up in the Gacha, she's just the gacha servant unlock once you clear Okeanos. So it'll be better to just wait for her rate-up, or throw quartz if you can't wait.
Edit2: Apparently, the reason why a lot of people are getting less CEs is because they decreased the rates of 3-star CEs in this event.
