The completely inexplicable movement of the vault is not appreciated by any player I have seen or spoken with. It has been moved to a place it does not belong. It is now extremely inconvenient to reach, involving repeated multiple button clicks. The "Profile" button, where the vault "tab" is now located, experiences a delay of a second or two every time it is clicked, and sometimes freezes. Absolutely no one asked, requested, or suggested this change. No one is pleased with it. It simply does not work.
We are smart enough to realize you moved it to emphasize the "Add Funds" button you replaced it with. I promise you, repeatedly badgering customers for their money is not good marketing. People see it so often, they reject it on principle. We also see that making it more difficult to reach the vault is meant to increase raiding by delaying players' ability to vault their money. This is not working either, and is a really backwards step.
Please, nobody appreciates the vault movement. There are so many other changes and suggestions that your players have taken their time to submit to you. We are not afraid of change, contrary to belief. I look forward to seeing how the new Inventory system works. I enjoy new sorts of quests, units, and rewards. We just don't want change that makes things worse. This forum is for feedback. The feedback is: it's pretty much universally disliked. Please move it back.
