He's really not that hard at all. Honestly, the hardest part is Gorgon's Labryinth. You make it seem like HM Templar is impossible. Last night, the Raid team I was with (guys I had NEVER played with before) beat the Templar without wiping. Kill the oracles on the side that he teleports to, burn his shield, damage. Then repeat. Once again, not that hard. Git gud
