2.2 Retainers via Microtransactions

[Naunet]

This is the only thing mentioned so far that even remotely suggests any milk cow or p2w possibilities, otherwise them doing this cant be called anything different than paying for "mules".

In every p2p MMO out there, your access to inventory space and market board usage is not restricted behind an extra pay wall. FFXIV is a p2p MMO and thus it should be no different. It's really as simple as that.
