I would really love to see better looking mage pets as well. Preferably some unique ones that don't look like mobs models. =) I remember my Necro in EQ2 having a vampire pet. That would be awesome for a high lvl pet =D And a fearsome looking undead warrior would be cool. The elementals need some love too, not that they look bad, but I think they need to look a bit more unique.
That being said, the new pet models look awsome!
