Just looking at the new retainer features, I almost see this as being an inevitable next step for retainers.

Imagine, being able to summon a retainer like one would summon a chocobo... and have that retainer fight alongside a player. It probably wouldn't have nearly the amount of combat effectiveness as an actual player (between retainers only having classes (no jobs) and probably being slower with the skill usage), but it could be really useful in future content, especially if a solution gets ironed out where players will be able to summon companions in dungeons.

IMPORTANT: This thread is under the assumption that, if such a feature were to be added, then there would be retainers added to the system via quests rather than needing to be purchased from the mogstation. Please, please do not turn this thread into a complaint thread towards mogstation retainers. That is not the topic at hand.
