While you can heal any content with any power, most groups over look nature and sorcery simply because they don’t have a 8 man shield. Maybe the next healing artifact could add a shield to the supercharge at lvl 80. Increased healing at 120 or visa versa. At 160 increased shield strength or healing from sc. I am mainly talking about the exclusion from elite raids. Burning terra during 1st phase, tentacles Ttbe.
