why is climbing and entering a new division so terrible?

small rant, but I feel like there is something systemic about what I've observed.

First off, climbing to a new division. Can we just skip the first series all together and go ahead and give us 3 straight losses and then make us get to series again? That's what happens nearly every time in my experience anyway. Wether its getting people on your team who are on tilt, afk / bad internet connection, trolling, inting, whatever, the first time I make it to my series in any division I lose every game until I am disqualified and then must re-qualify. Just lemme skip that step please.

AFTER ENTERING A NEW DIVISION.... is it just me or does the same exact thing happen? you're sitting there at 0 LP just looking to gain 20 or so so you aren't at zero anymore, but you get trolls, inters, ragers, bad connections, etc. This has cost me a demotion a few times. I really feel like because of the pattern there is something in riots system that intentionally tries to fuck you as hard as it can when you have zero LP, or 100 LP, everywhere in between is kind of a mixed bag in my experience.
