Can't blind mode have position choosing before queueing ?

I mean think of it: You still have all the lovely components of blind such as no bans or no spoilers to your team's picks BUT you don't have to fight over your role and ending up going Draven support just because that 0/9/7 lvl 4 Vayne "Smurf Main" says ADC after you said 10 times ADC and like he doesn't give a flying f*ck about you . Think of it: The Dodge rates would go down by 79%! Riot, Please do this at some point and time
