That would be an amazing Titan-specific move for the Monte Carlo and the Duty Bound. Hell, make it a fucking cutscene to intro it. Imagine a line of Titans facing down a mass of charging thrall.
Zavala: We're dry and the Thrall keep coming! Ikora: Get your men out of there, Zavala! There's nothing more you can do! Zavala: If we flee, thousands of the City's people will die. We hold! Ikora: Zavala!
Titans hold.
Zavala: WE HOLD! TITANS, FIX BAYONETS!
Titans fix bayonets.
Zavala: FORWARD!
Titans charge with a mighty shout and a cloud of flying Thrall limbs and melt through the Thrall like the Rohirrim carving through the Uruk-hai.
