World boss would need some mechanics to make it challenging (bullet sponging time consumers lose their appeal after a while). Nothing stupid like detainment bs, was thinking more like AoE moves that one shot guardians inside the radius, or subtle crowd control moves (like gutrot's mechanic, but not everyone at once). Also make there be a reason for controlling who the boss is aggro towards (don't have an idea for this, besides a presence of crota kind of mechanic)
