Is it possible that a set was only adjusted in the patch notes and not in the game? The little dino's damage isn't instantaneous, but rather has the same delay as always, and it's also summoned. So you wait over a second, or rather two seconds, for the damage to the puppet, which is a real shame. Or did I misunderstand the information?
Maybe it no longer counts as a companion, but it doesn't deal damage to the enemy any faster.
