Try out Wanderer's Guardian with Mace/Focus (and Staff) with Harrier stats. It's not viable anywhere as a healer or with buffs... not in Fractals, not in Dungeons, not in Raids (though expected) not in PVE and... well nowhere else. PVE has no friendly healthbars and there's no incentive to random open world parties so few actively invite others to free-roam, so no healthbars show and thus healing others is harder to gauge and kind of pointless. Why has Guardian Mace and Hammer been so neglected for so long? Is it just yet another case of more ZERG or go home?
