So... I kept track of my R weapon pulls from the gacha recently... maybe that 120+ one was high luck cause i've gotten 62 once, 78 just now, and the time before that was 95 R weapons... so out of what i'm keeping track of, i'm averaging about 88-90 R weapons every time i exhaust my draw count...
i'm not going by "out of 1000", i'm going by "out of 1100" cause I pretty much drain the gem gacha as much as possible
at least it's a few runs to try and get some more exp than usual
