Too many people slept on the Seraph Tower event over the past few weeks, and the new Seraph Tower activity has just become an insurmountable task to complete, even if you have a full instance of 9 max-power Guardians. Giant bullet sponge Servitors shield EVERYTHING, including other Servitors, rendering all enemies immune to any damage. Once you progress far enough, ALL THREE SUPPORT TOWERS are active at once (two at once from about 10% to about 80% progress and each completed Support Tower cycle is only worth about 5% progress toward the overall goal (rather than the ~14% previously). Just drop the damn Almighty on the Last City and be done with it, Bungie. We’re doomed, anyway.
