Actually why Warmane - or the Developer that codes here, bugged the Prepot with PVP Trink per Macro? And it is just the Macro use bugged not the Trinket itself. So is there a special Reason for it, that you remove a Feature which is also working on Retail?
And btw i know that the buff gets removed in Legion, but that has the Reason that mostly all Trinkets dont have a "use" option anymore especially in PVP. It was removed with MoP, so pls dont compare Legion to Cataclysm....
