You seemed to not understand how Passage of Arms gets used in practice. You really don't need to channel it. That's why we corrected you on the subject.

As for why it matters? Well, every expansion seems to give us more and more mitigation tools. I don't think there's a point for every tank to have two raidwide mitigation actions on top of Reprisal as a role action. It just seems like overkill. It makes more sense to dial back PLD, than to add an additional action on every other tank. If you're struggling with using PoA correctly, which it sounded like you are during your initial complaint, then perhaps they should develop a functional hybrid between PoA and DV that serves as PLD's single raidwide mitigation tool. You really don't need to have access to both.
