Whenever i climb a division i always lose the first game. That's ok.
Also, my lp gain/loss becomes more or less equal like 18 to 21 for win and 18 to 21 for loss too. After some games, around 7/8, in the new division where i tend to have a 50% winrate in the end of those 7/8 games.. when i get to 0lps it just takes 1L to be demoted, like wtf? It happened twice in different divisions ans makes it really hard to climb
