The crafting materials really do need a revamp and I think we are getting that too (yay!). But in addition to more retainers and a mog house suggestions, a bank would be cool too. It's something I've seen in other mmos and thought was nice to have, just a place to store money and items you want to keep but don't need right away or all the time. Also banks would have to be accessible from ALL cities and be linked for convenience.
