Please leave the gator, I wish they would bring the gator pet back instead of the basilik. Perhaps the old graphics issues with the pet model have been corrected by now.
Id be satisfied with gator or basilisk, as long as the warder matches the beastie. Just looking for a little consistency.
Perhaps the best solution is to allow pet classes a choice of which pet is used. Maybe some sort of drop down menu to include both newer and older versions of pet models. For example, ogre shaman could have a drop down menu of brown bear, polar bear and black bear. Iksar beasts could have any animal that cowboy boots can be made from (sorry, had to throw that in there)
*cough* I call phantom froglok for necros then (it was a raid pet once, I forget which levels, I think in the 80's)
