I'd like to see a Fenrir mount added like the WHM Unicorn.
And of course I'd love to see more SMN avatars added, however my question is, why? We have a Ranged DPS, a Melee DPS and a Tank pet already. What other role is there to fill? Maybe a healer pet or a support pet? I guess there's still room to add more pets.
It's just that without elemental resistances/weaknesses the point of adding more elemental pets is moot.
