It does not seem intentional that an expert pet has double stat scaling. My friend who had 150 int at about level 35-ish had a pet with 350 int. That would explain why mage pets are causing summoners to go toe on toe with warlocks in AE fights. Single target, Sorcs do not stand a chance against summoners because of the nightshade pet making up 60% of the parse. Cool when aside from auto attacks the second highest ability is dealing less damage per second than 6 pet abilities. On top of that, sorc's are pretty bad for PvP while summoners are great at it. Perhaps tune down pets.
