Everything is on default, my gear is V high end tho (cleared 63 GR manually) from what I can see is that your maybe missing a decent Ancient Yangs, the resource cost reduction is huge and you'll be firing alot more multishots more often. Also im using calamity/elements ring in cube.
Ive noticed your Season, wheras im non season, so ive had considerable amount of more time to get better geared compared to you
