Well your FeiX stats are really bad, my FeiX is 87/186 and can 0 cycle with march 7 instead of robin. Check if you have any pieces with less speed and more crit and atk, your feiX only needs to be 1 spd faster than Topaz. Gallagher should be using Quid Pro Quo, and he should be even faster, BE is not very important in this team. Robin build is fine. Topaz crit rate is too low, try to hit at least 80 crit rate while keeping that crit damage, there's a lot of cdmg buffs in that team so you dont need to have high cdmg.
