For pure thrower and not hybrid...
Go like 21/18 with at least 100 points in polearm and carry at least 1 throwing lance to melee with. It's a pretty solid melee wep, basically a short spear you can spam with to defend yourself. Once you have thrown 2 of your other 3 inventory slots of throwing weapons to clear some space in your inventory you can then scavange some polearm off the battlefield, and then throw your lance if you want.
6 atheltics isn't a speed demon but is decently fast in leather or cloth armor you'll easily be in top 20% in terms of effective run speed on the field.
