Honestly having bad luck here

No, not hex tech chests )though I would like some chests to use my keys on =n=), bad luck in match making. The main cause being well...several reasons. Now I can go into quick play but then what ends up happening then is either A: unorganized line up costs us the game B: a ranked player or twp on the enemy team (still dealing from that goddamn taliah jungle...) C: bad teammates (how did you expect level 3 Lucian to GANK? Now your gonna feed and ruin the game for all of us???) Mostly it's been the last 2 reasons. I've yet to figure out WHY a ranked player shows up in the quick play and of course I'm open to players that ARENT walking bio hazards, that would be great. But seriously is there a reason for a ranked player coming into quick play other than wanting to, as my brother says, "scrub stomping"?
