since i want to play dark as secondary i think i will keeping the SSRwep separate at 0 uncap and skill them up. 3x copy of 16% ATK boost and 1000ATK is stronger than 1 copy of 16% ATK boost and 2000ATK, and hi stat can come from other wep slot.

maybe it depend how many in shop and if it is possible to drop from the boss. i think i will collect them individually and decide after end of event.

i recommend that advice to new player as well. there no reason to quickly combine SSRwep until grid has a lot of other SSR. individual stat is great even at low level.
