You're not exactly as tactful in your debuffing decisions if those were/are your NW actions.
Trust me, I've played an FB for 3 years straight. From what I know you were a Wiz for a good while. If you can do dash combo with any decency, there is almost no need to root FA. Only WI. FS should be the one's you darkness. Wi and FA are ranged by default, why choose a skill on them to slow them by 1 attack? You seem to not take into consideration how much time it does take to debuff, even in combo. HL should be primarily used on WA as they have the highest HP, or FS ifWA is not present. BL are similar to FB with just extra stats, but an FB's rate should give them the leadway.
