I had my suspicions last week but put in another week to make sure. Before the Kowloon event, I was getting RSM every two SRS runs. These past two weeks with weekend boost and not one. Same equips then and now too.
It was Rising Sun Marble for creating the clothes set there. I have a much stronger set, it's just something I never got to when I played years ago. Consider it checking off a bucket list. Before I made this post, I had saved up nine and only needed one. Oddly enough, the following run the next day I did after making this post had dropped two. Went from 0 drops in 14 runs to 2/15. Don't know if someone got involved or RNG showing mercy, I'll throw a thank you out there. Regardless, the set was completed. I'm moving on.
Oh I see that's cool. I also sometimes like to do old dungeons for nostalgia sake. Member when SRS was the place to grind before release of Tibet map? I member. They nerfed or reworked how the drop rate works like 3 months ago I wanna say. You need noticeably higher drop rate % to get the drops on same frequency as you did before the change.
I know for sure that I got my first nine RSM after the drop rate rework you're talking about. I thought they did it again since I had ran SRS 14 times without the marble dropping. I was fine with getting one RSM every 1-2 runs, but if they didn't change it again then 14 runs without a drop is insanely bad luck.
