Well, I’m just taking Blizzard’s word at face value. Quote: “The cap we added for Animosity was primarily to help keep the extension gameplay healthy and not reliant on effects like Power Infusion.”
Sure, our 4 piece and future proofing the gameplay might contributed somewhat to the decision. But they literally stated why they were doing it now. I’m not going to try to analysis what meaning their word could’ve meant, instead of what they meant to me.
