match making is complete bull

The past 2 days now match making has been completly incapable of properly matching correctly matched teams, i keep getting bronze 5 skilled team mates well being made to face off against silver-gold ranked players for every match no matter the que i used(blind,team builder,draft normal) and i just cant understand why the system breaks when i do manage to actually pinch out a win in an extremely up hill battle, cause so far no games have just been handed to me like they have been to all the enemy teams that keep winning the games im matched agianst cause the matching system deems they just get free pass to win, by either making so they take next to no damage with just getting 1 item or allowing them to 2 shot us even when we have full defense build countering their damage type and they have no pen items yet they still wreck people in just 2-3 hits, i mean seriously this crap is just not fair, expecially to me forced to deal with this crap every game all day straight, only way was able to get win of the day is by playing a bot game were it had no means to give me an enemy that was out of my skill level, im dont even have a ranked status cause i hoped it would keep me out of the bronze 5 groups but god this is just ridiculous.
