I believe there are 2 cases where there is no visual information for what is happening, and even a small information would be useful.
- When a key is found.
In fort and convocation a key must be found to open the grimuar chest, yet no information is given whatsoever, that one of your teammates has found one. In good team it is customary to write something, but the game should really tell us to avoid having to write this. This often leads to situations where somebody has found the key and proceeds with the map, while other teammates are still looking.
Visual information very similiar to one displayed when teammate gives you potion or bomb would be excellent, I think, only pointing at a key.
- Natural bond
Similarily to above, when teammate currently has a “natural bond” trait, it requires explaining in the chat. Visual information around players health bar would be a much better solution to this, removing the need to explaining in chat.
However I have no idea for a specific solution, sorry.
