Game mode idea: Solo Queue (no, not that one)

TL;DR: New 1v1 ranked queue mainly focused on getting better in the laning phase, special pick/ban and rules in place to fix the usual 1v1 problems.

Im a Diamond IV-ish support main, and I had an idea about a new 1v1 ranked queue, which I think would be fun and increase the level of play for 5v5 at the same time. It would be played on a modified version of Summoner's Rift and would have a timed ending(like 15-20m,basicly just the laning phase). The winner is determined by who has the gold lead at the very end, and your LP gain/loss would depend some on your gold difference. (In the match you could see the gold for each team at all times.)

You could queue up for it with selecting your lanes like normaly (except jungler ofc). I imagined the champ select for solo laners like the following: First you both draft 4-4 champions in A-B-A-BB-AA-B format, then both of you bans 1 champion of the enemy out of the 4 picked, and then you blind pick your champion out of the remaning 3.

On the map minions would only spawn on your designated lane, jungle camps and other monsters would never spawn. I think a game mode like this would be popular among casual and hardcore players alike, its short(20min max), easy to implement, and would be a good way to learn lane mechanics in a ranked-like enviroment without wasting 4 other peoples time, so when you finnaly head into 5v5, you can concentrate on the macro aspect of the game.

I know that without junglers many matchups would be played differently, and most games would either be snowballed or become a farmfest, and this is why I though your LP loss/gain would depend on you gold difference at the end of the game. So the loosing laners would need to play safely while still geting gold, and the leading laner could make more reckless plays (like turret diving) to increase his lead (and so his lp gain) even more.

I think this game mode would have enough strategic element, that it wouldnt boil down to a simple "Omg I got countered, I better FF"(btw you could FF at anytime,but makes you loose Max LP), and myself would surely welcome such an addition to the game.

P.S: This would work for duo laners too, but I hadnt thought about how the champ select would work. Also excuse my english, feel free to correct my mistakes.
