A Small Change to Ranked?

So currently to go to division 2 to 1 you need to win 2 out of 3 but really you need to win 3 out of 4 with the first game being an absolute must win.

I propose you start your series with the game you win to reach 100 LP. Meaning you are at say 90 LP you win and go into your series you are now 1 win out of 3, so you only need to win 1 more time. I feel like this is way more fair because honestly at my MMR its completely random whether you win or lose. Its very heavily reliant on your teammates not feeding rather than you doing good.

This is hard to carry:

4/9/12 Yasuo
1/9/13 Braum
I went 11/4/10 Cho...
2/8/12 Ekko
6/10/6 Graves
0/10/9 Shen
I went 11/8/7 Lux...
1/7/2 Malz
3/7/2 Diana
admittedly i went 0/5 as J4 and thats on me...
This last game was 5/8/12 Graves
1/13/11 Blitz
i went 5/6/15 Lux... not good but i didnt feed.
Funny story actually the Diana that went 3/7/2 went 15/3/13 as Jinx against me in the next game... so idk what happened...
