It's not a pet system it's a partner system to use your Chocobo in your party. Vanity pets require new models or models that must be redesigned, new animations = resources/time and not everyone believes the dev team are full of idiots they just believe it would be more useful to add something that's more important rather than fanservice to satisfy people who crave to have some small animal walking behind them. You want a pet play a Summoner. And just because someone has a low post count they can't post an opinion? Yet you also had a low post count before didn't you so how does that make you anymore special?
