Paul Farquhar
Legend
As others have pointed out, the problem lies with the quarterstaff, which is OP in this edition. Probably because of the coolness factor. In earlier editions it was 1d6 and required 2 hands. And I houserule that Polearm Master works with a spear. Who doesn't? Or follow 3rd edition and have longspear (with reach) and shortspear as different weapons.
5e really has too few different weapons, not too many.
