Segwit WILL eventually help reducing fees, but it's going to take time. Users need to xfer funds to the legacy "1" bitcoin addresses to the segwit "3" format addresses. It would be helpful if the exchanges and payment processors (I'm looking at you Shapeshift) sped up their adoption. Last I checked, segwit txns were now around 5% of the blocks.
Fees are important, but the main positive of Segwit is that it paves the way to 2nd layer protocols like Lightning, etc.
