If it takes 2 wins to get into a tier, then it should take 2 losses to drop out.
I am really frustrated with earning 80 LP, can't make it to promos, lose 20 LP a loss, then drop down to 0 and next game get instantly demoted.
I can't control that I'm with a sexually-harassive Galio support, or a Rengar support who won't ward, or a Master Yi who can't team fight. Trolls are in the game and they can't be eliminated. But what can be fixed is the annoying mechanic of the game where if you tend to stick in a tier for a while, you will go on a huge loss streak with trolls/feeders in yours games (there's no SOUND proof this phenomena exists, but its happened to me so much I just label it as the "Slow Climb, Fast Fall" Theory.
Anyways, the point of this thread is to point out that it is not fair to struggle to win two games to climb and have to lose one to instantly be demoted. That's demoralizing and wrong.
I feel like we would just have to change the demotion timer to be a constant two losses (except after immunity), that way the games that end we won't feel that pressure to see the dreaded "DEMOTED!" message.
