Ive got mixed emotions about this. I plan on going arcanist main at launch. But what i dont understand would be like this:

As arcanist, i got carby out. Well, ive also got my chocobo which can fight alongside me. Oh yeah i also have ,my other pet too. And eventually we may get companions back. Im a die hard pet class lover but even i could see this being redundant.

Only way i could see this working is if you dont have to just pick a chocobo for that content. Like, instead you could have a few different types. Personally, id like to see a tonberry, cactuar, ahriman, or malboro ^^.

On a side note im gathering by that pic, maybe certain pets increase your on char. Inventory?
