Make the linked game accounts visible, if I link one of my 2 or 3 Riot Games account i want to be able to see which one is conncected and possibly have a switch between them. That would avoid people to claim objects on the wrong account as it happened to me and loose 1 hr with the support to ask to change the accuont of the reward, thing that they are not able to do.
1: Visibility of system status
The design should always keep users informed about what is going on, through appropriate feedback within a reasonable amount of time.
When users know the current system status, they learn the outcome of their prior interactions and determine next steps. Predictable interactions create trust in the product as well as the brand.
Good error messages are important, but the best designs carefully prevent problems from occurring in the first place. Either eliminate error-prone conditions, or check for them and present users with a confirmation option before they commit to the action.
There are two types of errors: slips and mistakes. Slips are unconscious errors caused by inattention. Mistakes are conscious errors based on a mismatch between the user’s mental model and the design.
