I'd like to see a very detailed pet system, not the same stuff we got in XI minus PUP which was a pretty interesting system with the attachments. Rather then charming, I'd like to see capturing, perhaps each residence can house 5 monsters with expansions if you obtain the proper Carpenter/blacksmith/armorer materials +gil to produce the add-ons.

The capture command would be just like the archer auto-range attack in the sense that it would not count towards the 15 ability limit and be an ability you have from lv 1. When you capture the pet you can mate it to make creatures with unique traits and such but the overall idea is each pet class should have a heavy reliance on crafters/gatherers. For BST/Tamer this would be cookers and botanist/fisher to gather the ingredients needed to make pet food that allows you to raise their stats.

For automatons it would be a combo of blacksmith/armorer/alchemist creating devices used to enhance the performance of the automaton.

Avatars could be a combination of goldsmith/alchemist/ to create enhanced gemstones which increase the astral energy of the avatar you summon.

I just think a method like Charm wouldn't be useful in this game considering how weak mobs are the same lv are aka how easy they go down, it really wouldn't mean much to charm one to use in the grand scheme of things.

Though personally I'm trying to hold my breath and hoping that SE will show us some class concepts they have for mechanics that have yet to be introduced lol. Even if it's an alpha concept I'd like to see what they have in mind when they think of a pet class in XIV.
