Forced lose steaks in blind pick+aram

Can you at least remove that f**king annoying and broken 50% winrate system from casual gamemodes at least? I mean, it's completely trash in ranked already but can you keep it the heck away from normal/fun gamemodes? It's irritating that i come home from hard day of work, wanna do my daily and want to watch a movie after, but end up playing 3 hours/6-8 games where enemy has 29/4 ezreals, 11/3 anivias and pubstomp dariuses every game where ganking your team doesn't do jack shiet but only prolong inevitable... Like cmon people, aren't you supposed to be smart and make games enjoyable not a chore?

Edit: Lose streak finally over, but FFS people, fix your s**t, i have put too much money and time into this game for you to make it worse day by day (and by YOU i mean whoever is in charge at Riot CO of gameplay changes or matchmaking system) :S

Geez pardon my language but something needs to be done not ignored, plenty of posts over 100-200 upvotes out there that ARE SEEN but just ignored cuz you know, money...
