well, up to now i managed to clear all this missions in GO, so if i keep it like that i'll have 5 every 2 weeks
the thing is, dark isn't my main or something, but i've thought to FLB both apocalypse lance whe the time comes+3 ride axe as they are also defender and the new union SSR weapon
and it'll require a lot of them, and before that we'll have more event so maybe more options to FLB
