I actually enjoy his fight. My issue is the stupid Tormentors that should never be in such an arena that has barely any cover, said cover not being safe due to Calus causing death pillars if you stay there too long, and infinitely spawning ads everywhere in the arena. For Calus himself, I actually found his mechanic to be a decent fight and then it goes into a full on cage match. Loved him in Leviathan and loved killing him in Lightfall. Now the Witness and his subjugators being able to one-shot you...
