I don't mind that they have Vanity pets at all, but it bothers me that they are using the term to make it more enticing like the other mmo. They aren't really companions in the since that they don't DO anything, they don't keep you company, they are just there for show. Call them what they are, not what you think would sell more of them based on what another game is doing.
it seems like a small effort to make a quick buck. Sadly that seems to be all that this game stands for at the moment.
