Warden is a 'boring' class

[Chaos Laicosin]

Without changing the class too much, there is the option to add different types of arrows. Things like higher damage with low flight speed for defending the cades at close range, or lower damage but some amount of armour negation so that body shots will deal appreciable damage, or single ammo teleport arrow so that they can escape danger, or single ammo blast proc arrow for precision barreling. Just some ideas.
