Mid lane allocation

hi I'm a mid main i play a lot of katarina and i used to taliyah mid lane and I'm s1 making my push to gold 5 and my honor rank is 1 (because i just got punished)

lately as in last week or so when i've queued up in normal trying to practice mid i get jungle or my secondary role at lot more times than i do mid, for instance in my last 40 games only 13 of them i've gotten mid lane and i had to beg for that role when i didnt get it, its really annoying and frustrating when the main thing i enjoy when playing league is being able to play mid lane, I've mastered champions in other roles and i know how to play them but i do not find them as enjoyable as mid lane katarina, i've mastered jax jungle nasus top and taric support and i wouldn't play league of legends just for them, if i could never play katarina or mid lane i'd probably quit the game and its my last season for partly that reason and its so annoying and frustrating i cant get what i want from league of legends which is so simple just a lane.

and I'm sure a lot of others have this problem and is very frustrated about it so I've wanted to propose a very obvious idea

can we add an option while in queue to choose only one role and guaranteed to get it, even if it forces you to wait much longer, for me i would love this i would rather wait 20 minutes and get my role than waiting 3 mins and not get it then forced to play a 40 minute game on which i do not enjoy

Here is my op.gg for anyone who needs proof on how often i get my lane http://oce.op.gg/summoner/userName=EdenCredits
