Yea i thought that as well. I agree with the change for supremacy and I think its sensible otherwise you had two 'pet boosts your damage' talents and it was shit how supremacy meant sacrifice invalidated that choice. But service is a bit of a fiddly talent to use for the average person (ie select it then choose the demon you want to spawn) so having that as the only talent for 'traditional' pets outside of demonology is somewhat tricky.
