I was just testing it on my phone and it seems very fluid, i need to try it in game still though. The expanded vault is coming sometime , i dont know if they are still working on it or didn't want to drop too much stuff on us at once. The combunation of the two will be nice. I'm sure there would be some kind of difficulty storing a potential infinite number of items on their servers, and maybe they're making sure it won't randomly delete all out stuff. Im hoping they roll it out at the same time as a kind of memory back up, so if someone's items or characters are deleted, there exists the possibility of reloading an automatic save from earlier at weekly reset.
