Hunting is not weak at all.
Study Prey+Flush Out is one of the most broken debuff in the entire game.
Call of the Hunt + synergies gives you over-the-top damage and speed.
Volley increases your general damage input by a lot, and because you attack more, you have increased chances to use shield passives from Defense (it helps with the spear being slower than other weapons).
Art of the Hunt too, and it gives you a ton of chances to avoid projectiles, which is a very good stat. Trail Blazing gives you quite some movement speed.
Herbal Remedy increases regen and gives a ton of poison resistance.
Wood Lore gives you a lot of Defensive Ability (combines with Battle Awareness) that makes you tankier/more prone to evade melee attacks + much needed attack speed.
You get good movement with Take down + Shield Charge, good movement speed, very tanky class, solid damage.
You don't have many AoE skills in Hunting for Spear (only Spear Dance, and it can make foes flee), but you have Batter, Shield Charge and Pulverize in Defense.
Finally if you really want to use a spear, Hunting is the best mastery for that.
You can check this guide, but Reflect is not mandatory for a good Warden :
