MMR resets/placements/matchmaking in general are an example that comes to mind where people get angry over things they often don't actually understand. Also, key fragment drops, and really balance changes in general. MMR is probably the most comparable example, since people get upset when they're ranked gold but get matched with silvers, which is a case of the hidden underlying number that actually matters (MMR) being lower than what they think it should be and not corresponding to what they see (their rank).
Is it fair to someone who has played honourably for years with their friends to not get any compensation just because they've exclusively played with their friends?
(Not talking about friends intentionally working together to spam each other honours, but the real group of people who only play league because their friends do, and so will pretty much always be in a premade.)
As a solo player myself I certainly have no personal objections if their reward criteria favours solo players over those who tended to play in premades, but historically they've always given incentives to group players (bonus ip, extra fragment drop chances, etc.) so it'd be an interesting precedent if the compensation here was biased towards solos (who have 4 potential unique teammates to potentially honour them every game) over premades (who have 3 to even 0 unique teammates to potentially honour them each game).
Now sure, they could be "Well, the solo players are interacting with more unique people, and making the game enjoyable for more people, and so it's fair they get rewarded extra right? Group players may be out of luck for this particular criteria, but hey, you had fun playing with your friends." but I dunno if that's realistic to expect.
