I have a tendency to get rate-up SRs at least, but oddly enough yeah, most of my SSRs have come to me off-banner. Frey, Atum...I tried for them when they first came out, but I stumbled into them only a bit later on. When I think about it, I think the SSRs that I've actually gotten on rate-up were the limited ones I have, namely Thunder Michael (my rerolled starter), Santa Satan (trying for Christmas Perun and had to keep going), and Dark Amaterasu (trying for Konohana-Sakuya and failed). The latter two were with gold/coins, though. Pretty sure that everything else I have was either a random get or a miracle ticket.
