Hi,
It is fair that whisper don’t restore your health, considering that you can craft healing items by yourself, but I think that a good addition can be restoring you weapon durability in case a player doesn’t have poweder to restore it. This can be a nice addition, considering that, right now, a I and others have to return to sacra if their weapon and gear are broken. This can be added or the possibilty to fast travel between sacra and other whisper should solve the problem. Yesterday I was in a dungeon and was forced to return to the city because my weapon was broken interrupting the exploration and the flow of the game in that moment.
