has an unreliable, active only, incredibly small AOE taunt

Are you aware of the fact that Barik's Iron Tolling improves upon reaching Act 2? It becomes a pulsing taunt that's mostly superior to Challenger Stance.

Pros:

• Always hits (I believe. There is no mention of Athletics in the tooltip, whereas Challenger taunt is an attack with Athletics.)
• Radius 4m is greater than Challenger's 3m.
• Taunt duration 11.8s > Challenger's 6.4s
• Pulse rate every 3s < Challenger's 6s
• Adds 2 armor to allies in 4m radius

Cons:

1. 30s duration, whereas Challenger Stance lasts forever.
2. Is an active skill, and is a combo so takes both PC time and Barik time.

The first con is not a big deal, since most battles are over in less than 30s, and most enemies are dead if the battle is still going at 30s, and Barik can use his other 2 taunts at that time.

The second con is not a big deal in most battles, as you can begin the battle out of enemy aggro range, using Iron Tolling to start the battle.

With Iron Tolling, all the enemies group around him, and then get AoE'd to death by the other 3 characters.
