Naming (sp?) pets is a great idea. Should be like your surname, meaning once you get it approved you're stuck with it forever. Mages could have names for all their pets, ie. fire gets a name, water gets a name, etc. And necros could have different names for the war, monk, rog, and spectre pet. Beasts would only need to choose one name, druids only one name. And well only because I saw someone mention wizzy pets....thats not a pet. Oh, I forgot chanters, I suppose they could name their pet too.
Awsome idea though, I don't know what I would name my necro's pet since most the time I just call him dummy.
