Guild Wars 2

Phalanx stance: Get into a phalanx stance. The warrior blocks all attack and Foes cannot pass through. Phalanx stance ends when the warrior moves then Phalanx stance becomes shield stance.

Think of this as the warrior’s version of sanctuary.

This suggestion is mainly for WvW. I imagine that three warriors would form a line and block enemies from getting into the tower or crossing the bridge.
