For what it's worth, the skills you're referring to were single-target javelin skills, which became AoE (able to hit multiple targets) when you had traited 'Area Targeting' in the yellow tree. As of U35, those two javelin skills and that trait have been removed, but that doesn't mean you can't hit multiple targets!
You have several gambit sequences capable of hitting multiple enemies. Your 'primary' gambit sequence for this is gambits which alternate Fist-Shield: War Cry, Brink of Victory, Surety of Death, and Desolation all deal damage to multiple targets in front of you. You can also use Spear-Fist gambits: Offensive Strike, Combination Strike, and Boar's Rush, which deal more immediate damage to multiple targets in front of you, but less damage overall compared to gambits which apply a Damage over Time effect.
If you haven't already, you might want to take a moment to become better acquainted with your gambit skills (they're on a separate tab of your skills panel). Gambits are where most of the warden's strength lies.
