I got no problems with a F2P model if the money is actually being reinvested into the games development. As it stands I have zero knowledge where all this cash shop money is going to and I still want to know why I'm having to pay for extra bank space via the retainer system.

If they want the shop to feel less of a cash grab, they should make better use of it, like using it as a way to fund building a new dungeon or armor set. Maybe even help pay for development time on fixing some cosmetic issues. If I'm helping pay for a side project to improve housing, or make it easier for derelect FCs to merge without losing their FC housing or something, that would be a thing I'd love to help with.
