"People in their promos should be paired with & against other people in their promos."
This isn't originally my idea, I read it somewhere else on the boards but I think this is a very important point worth bringing up again.
While Ranked is a game mode that is taken very seriously, promos will be the ranked games will ALWAYS be taken WAAAAAAAY more seriously because those 3/5 games matter a hell of a lot more than the games where you're trying to climb in your division.
Now, I understand this can't be done perfectly 100% of the time (I.e. You have a a duo and one person is in their promos and the other is not.) But I think if this concept was implemented would be amazing.
Sometimes, if a team starts to lose, they may not try as hard anymore because they think the game is already in decided and then you have that person who's in their promos who is trying very hard to make a comeback and encourage their team to keep fighting and not give up. While every ranked games does matter, someone who is sitting at like 60 ish LP may not care too much if they win or lose their game since they can just go and win another game and gain LP again if they lose that match but the person in their promos can't just go back and be like "Hey promos, my team didn't really care to try anymore so can we make the red x disappear?!"
It would also make the match-up a lot better for the people in their promos to be paired with others in their promos because these people would understand that they really want to win and not give up even if the match doesn't seem to be in their favor.
