very low elo players mindset

Like did u ever have a teammate such as the adc that just greeds for farm botlane when team is grouping for a baron play? What are these people even thinking, or are they even thinking, like such things is so illogical is really makes no sense. Jglers that are a division (gold - plat) plays like a absolute monkey giving the enemy team few kills then they snowball off that and not surprisingly win the game after you completely stomped ur lane going 5/0 and tower. Why are they even playing if they are not mentally thinking what should i do next, does my team need me, whats the most efficient play atm? are they just so fucking ignorant that they cant even listen to advise or plays that is the very optimal at this time? do they even deserve the rank they have even though they dont know wtf to build and as i see their build, im like wtf arent u suppose to know what u build if your clearly playing that champ many times? do they even do research watch vidoes on meta champs and builds to actually commit to climbing?

this is just a rant after experiencing players who does not use their brain to the slightest
