A remade ranked system: My crazy idea

What if we removed the requirement to win promotional games altogether but make the promotion require more LP? I bet I'm going to get verbally attacked for daring to suggest such blasphemy, but I have seen so many people saying that they lost because a player left, trolled, or just didn't do well. That said, i think that the promotional games add unnecessary stress to a game that is known to have its infuriating moments. On top of that, I think it's just a little bit too much. In order just to get to the series, you need to go on a hotstreak. If you pull that enough, shouldn't that be enough? The additional series you have to win is overkill. Now in order to balance this, I think that yes as mentioned before, a promotion would require more LP. On top of that, you can lose LP below the threshold of the required rank. When that happens, perhaps you have five games to get it back up before demotion? And no, I did not recently lose a series. I think ranked is too stressful to be fun. I just think that if this change happens, people might not be so hot headed in ranked games.

BTW, i voted that I'm a genius on the polls. I forgot to add an "abstain" option.
