Suggestion for ranked play!

I had an idea for ranked play and to me obviously it seems good and interesting, BUT that's why we need opinions:)

So firstly what i believe this will have an impact on: 1)some decrease in smurfs 2)there won't be much of a war for lane (yes it's gonna be also a suggestion to bring the old solo queue back) 3)some decrease in unskilled players 4)better understanding in all positions for everyone 5)maybe a decrease in boosted (animals or not) players but can't say for sure some are way too hardcore in this

To the idea: In order to go ranked solo queue you MUST have at least 1 champion with 5 mastery rank at every role,now this means 5 champs in every type of lane mastered in a degree.Also because this takes time to do (and it's mostly to protect newbies from banging their face instantly in solo queue,and not affecting veteran player that much except maybe one trick ponies) the above points of game impact come in. In addition for champion select i suggest you choose from the champion rooster YOU have mastered.You wanna play that yasuo? better know him well enough to perform at least decently.So a player for solo queue(before the match at his profile) may or may not select from a range to 1 through 3 (am saying a number haven't rly thought this one out) champions from his 5rank mastery pool at each role.For example you may rank with your personal rooster consisting of top:gnar, malph, riven mid: veigar, brand jungle: rek sai ,vi,Hecarim adc: twitch support:Taric The team sees each others personal rooster decides who is gonna go where with what champion and form the best team comp they can with what they provide and what the others offer.As for the bans each team bans from each others current rooster.This will help the ban phase to have more meaningful impact feel more direct and strategic against the enemy team and maybe some champion will see the ban spotlight instead of the typical ban rotation we get every season. In conclusion this will also help get rid of the dynamic queue and rito can bring back solo queue safely and it will probably achieve the same results if not better.The one thing am not sure of is if the queue priorizes with champion differences(and amount of champion selected in a role) in order to achieve the most diverse rooster, so you don't have senarios like 3 people in the team have 1 champion for top and on top of that happening to be the same champion,how long will the queues take then..... personaly to my ears this gives out a bigger range for the system to look at matchmaking than what it's currently looking for(lane preferences...come on we have over 100 champions! hope you see what i mean). This was it:)
