DQ boosting

So today i played my plat 3 qualifiers (for the 4th time) and every time i do i get into a REALY frustrating game, not because those are qulifiers but because of 2 reasons: 1. Playing vs a lower rank player (mostly gold 3-5) and then when he get's carryed hard being bullied by him whole game like in my first game or playing WITH a lower rank guy and geting flamed by him for being useless. The first qualifier i beat a fizz mid with an azir, tilll 30 mins i had like 3-4 more kills and 100 more cs then him but that didn't stop him from saying easy and flaming how much i suck whenever he killed someone or got an objective. In the end they lost cuz fizz got easy baited to go 1 vs 5 only to keep flaming me again saying i need my team to winn even though i killed him 1 vs 1 few times... The second qulifier i got the volibear from the picture. From begining it was obvius he couldn't be plat skilled player because he went all in into cho'gath on first 4 lvl's taking minion agro too long and pushing his lane all time, then when dying flamed our jungler for no ganks. When we got to tf's he would just run into first person he see's, throw her with his Q (mostly cho'gath) and kept attacking only him till he get's low health or dies. We lost that game because hecarim straight up trough my WHOLE team passed with his E and went for his easy combo to burst me down. In 1 tf i was runing for like 15 seconds around my team (using my ulty + barrier + flash to keep being alive) but team didn't ract to my pings and only chased enemy tanks resulting in me dying and geting flamed by voli for being useless and doing no dmg and i admit, i barely did any dmg in any of those tf's mostly because hecarim focused me hard from flanks and no matter how many times i told my team our comp ain't for engaging but for pushing and zoning they always ended up going all in into enemy leaving me to heca to cut me down easy... After the game heca told me he felt sry for geting a team who doesn't understand what it means to deff their carry and again i got flamed by none other then gold 3 volibear saying i'm just a noob with a 3/8 score not even looking how much dmg i did. I beg you, stop boosting your friends, they are where they deserve to be with a reason, they might have mechanics, they might have logic, but they are missing something that makes them lose and till they learn that leave them in the division they deserve to be. I get people who are boosting like this almost every second game. STOP doing it because we solo players aren't there to carry someone who does bad even for his elo !
