Kindred's passive tells you when Quinn switches to Valor
It was suggested that I make a Bug Report about this to get a proper response.
Kindred and Garen's passives use recycled minimap icons. This means that their icons get switched when Quinn and Gnar transform into Valor/Mega Gnar. This happens even if the enemy Quinn/Gnar is not visible to Kindred/Garen's team.
In the case of an enemy Quinn, this gives a lot of free information to your team, since it tells you all that a 140sec CD ultimate has just been used. Said ultimate is generally for either roaming quickly picking off low HP targets by surprise, and the consensus in the original discussion is that it seems to be an unintended function of Kindred's/Garen's passives. I think the intended use was that a villain/marked Quinn or Gnar would only have their standard icon in use, even if they switch into Valor/Mega Gnar.
