This right here? Where it suggests friends to invite to a game?
Well, what if we added a little indicator beside their name to the left that displayed which role they played the most? Say you need an ADC to fill our your team, but you don't know which of your friends has a hankering for the role right now.
Well, instead of going and checking up on them, you could just look to the side and see who plays what.
QoL changes are the best changes.
