My account was about 4 months old. So far, I only seriously roll 4 times:
- Summer Fran/Maid Alter/Lancer Raikou [summer]
- Merlin [after Nero Fest]
- Gils/Okita/Shirou [thanksgiving].
I spent 2 tickets on Gramps and Ishtar banners just to try my luck. The slash means any of them would make me happy in that order of priority. Amongst them, I got who I wanted twice: Merlin and Gils.
So my ratio of banners which I achieved my goals / total banners seriously rolled is roughly 50% which is pretty good.
Certainly, there are more factors involved in satisfaction such as the total number of SQ spent. I don’t feel the total number of SSRs obtained matters much when it comes to satisfaction if those SSR are not who you really wants. So for simplicity, I think the ratio I defined above is a good indicator of how satisfied a player is.
Let’s say “seriously rolled” to mean roughly “spent (or intended to spend) at least 30 SQ/10 rolls”. What’s your gacha satisfaction score/ratio?
EDIT: Add “(or intended to spend)” to account for people who got the Servant they really want in a few tickets.
