I've never liked fabric softener coz it feels sticky after the washing is done. I know some people who use it like a laundry cure-all... And I never like sticking technical fabrics in the dryer. It air-dries so quickly. Better for the environment that way right? less dryer use?
Air-drying is nice for any wicking tech. fabrics.
I've never used fabric softener in my life nor was raised in a household that used fabric softener and can't see any compelling reason to do so in the future.
