If we all step back and look at the bigger picture we can probably come to one main key point. Inventory wise the game is designed to accommodate at average 3 classes and that is with low end hoarding habits. Having extra retainers semi helps and really only makes the hoarding habit expand. For those who are organize and constantly have a flow in there inventory having extra retainers can help in terms of selling. ( mostly if you craft ) Sure we all like to keep glamour and such and hopefully they can expand the Armorie options, however if we really look into our inventory why do we keep most of the crap?
I'm guilty of this and have max retainers, however it does help me gathering materials and selling. I have a Private FC as well for space and perks. It's still better than alternates and spending more money on multiple accounts. -.-? SE is meeting demand and lets face it us lazy people would rather pay than be more organized -.-/
