The Sargeras raid was done all wrong. We should have resurrected/healed/freed (or whatever, I forget) the titans and then the titans should have fought him but we controlled the titans. In this unique encounter, you have titan talents/spells but it’s different depending on your role e.g. tanks, healer, melee dps, ranged dps.
But as was, Sargeras was defeated by a protoss lasso.
