Riot you can do better than this with MatchMaking

Riot you can do better than this. I get you are trying to balance average MMRs to get faster queue times and premades skew the variance of the players, I really do.
However, and be honest with me, how am I supposed to have a fun match when I proceed to roll my face on the keyboard to beat my opponent with no challenge whatsoever, only to then lose the game at the 19:00 min mark because all my teammates are inexperienced and fed their lanes. There most be something you can do for low population servers like LAN to improve normal match making, there most be.
I don't care if I win or lose a normal game, I really don't. However I want to have a fun game were I get to feel like I had a meaningful impact in the out come of the game. I play normals to play fun stuff like Teemo and such, so I don't want to have to absolutely tryhard as a jungler or mid just so I can keep the game afloat every single time. I want to have fun playing Top lane Teemo, or maybe mid lane Varus. I know these champions don't carry as hard as others in these positions, and I understand I can't expect to have the same win rate as I do on rek sai or warwick jungle; this isn't about that however.
I expect every lane to have a similar MRR rating -- maybe you can use predictive algorithms based on histograms to determine which role is more likely to play each player on blind picks, I don't know. I just know that being on a losing streak because I don't have my carry pants on normals is dull and boring. I can't flame my team mates because it is not their fault their bronze butts got pitted against plat 4 players, but I also don't want to play against incompetent players that hug their towers because their plat premade told them to and be reduced to freeze farming until my bot lane inhib goes down and then get chain ganked by the mid and jungler 3 times in a row and lose the game. I think I am being reasonable here
