200: good, lacks only implaccable and has only 1 pet, but high agi (168) and rather high total points (267).
300: same as before: only 1 pet and doesn't have hypnosis to counterbalance the lack of pets
500: has now implaccable, but unfortunately still only one pet and no hypnosis. From what I've seen this can be a serious handicap. Too bad it doesn't have herculean strength as well.
Imo this is a very good brute at level 200 but then at higher levels it becomes comparatively weaker. Anyway, I however think you know better than me how to rate brutes ;-)
