I don't see how an immovable ally forces you to not retreat. If he chooses to sit there without retreating with you, leave him. Make the ult turn off fairly quickly, maybe with a speed boost like Xerath.
If someone gets hit with a ranged stun while your team is retreating, you don't stick around for the ace, you trade 4 lives for their death.
In fact, this would be a lot like Locus of Power. Except provide a defense boost instead of an offensive one.
