There are some [Arena Fighting] feats that make a Shield & Tratnyr Fighter more interesting, including an at-will reach attack, and a free heavy thrown attack option.
Correct! There is a cleave-arena-fighting feat that allows a throw attack instead of the damage to an adjacent target. That allows two marks on an at-will for sword-and-board users. Also, its a Dragonborn spear that works with draconic arrogance and all the other spear feats.
As far as I see, they work with it - but they still use Dexterity, not Strength.All the Ranger powers are Str (melee) and Dex (ranged). There's no Str (Ranged). None of the Ranger's powers work with a Heavy Thrown weapon.
