On a side note, I am yet to play a Dex fighter as I am in love with Polearm Mastery for fighters. Hit -> Spring Attack to disengage -> OA when they close again is just good fun. The enemy start ignoring you after a while, so you swap to knocking them prone etc. I hope that feat makes it into the PHB.
Sorry is this from the play test or somewhere?
