I was personally not a huge fan of pet classes in XI, although many people were. They just seemed kind of hmmm.. lonely? Most of them were solo jobs (well... 2 of the 3, excluding DRG even though it had a pet). I like to play an MMO with a group. If I wanted to solo I would play an offline game for that personally. I do like the chocobo concept, as long as it's done right, and as long as the AF gear for choco's don't end up looking dumb.

So I will take one of the latter options and adopt a rock.
