If you are playing with people who are far better than you, you're going to get owned anyway and lose the mmr.
What am I missing here?

you are missing that kids think they are better than what they are.

^ this guy knows

I had trouble to get out of the 1600 bracket solo, was 1680 forever.
I know I can handle 1700 games since my other account is ~1750, asked for a boost to 1750, hanging around 1750, even climbing slightly.

soloQ is just hard, 1500 is np's soloQ for me, 1650+ gets harder.

Did it answer?

Honestly I don't see the point. Unless someone is helping you out for free. There is absolutely no reason to boost and pay for it in any way.

well if someone have the intention to get better boosting could possibly help

example

1600 player gets boosted into 1800 bracket
even if he loses every single game it will take him like 30-60 games until he is back at his 1600, but if he is trying to actually learn from the higher bracket he might not drop down to 1600 and stay at 1700


ofc 99.9% of the people playing this game dont give a shit about getting better they just play to play


but well yeah


oh and btw, instead of paying to get boosted to 1800 and learn from those games simply find a honcast player you like and download replays of some of his hightier games and learn from there

I was watching some replays / youtube videos of good players on the heroes I use and learned a few things but it's basically knowing what other heroes skills are, cool downs , etc

for me, i've always loved to make high mmr ppl lose because all think they are alot better than rest
specially people who smurf or have high win% or high kdr those are the best games to throw

the key is not to make it obvious and not to get mad or flame anybody on the team
get caught somewhere: sorry guys i was going to ward, or sorry needed 100 gold for w/e item
when team pushes and your team gets genocided make sure you are halfway or further across map without tp and use that as excuse when whole team pings on you
in big tim fights make sure u miss stuns or target wrong people (if u r pyro or ws or etc use ulti into null stones and so on) because this might not even get noticed and if it does it can be atributed to bad plays

i also find it funny to pick junglers like legi or sols or w/e if u r lowest mmr in team because every1 else's ego will get hurt having to support and they either won't do it or pick only carries or heroes that need farm
if you account is boosted and you can claim mid this is even better because u will get owned and again keep calm and always find something to blame i.e (their mid had haste or dd rune or he was lucky etc...)

Subtle trolling is an art, and you're an artist lol
I agree though, a lot of people in these RTS games are extremely arrogant with how they play and it defeats the purpose of teamwork.

u make me happy.
i want to play with you.
