Changing Draft Matchmaking for the Better

So, I've held this opinion for a long time, and I think that in draft and Ranked games, you should be able to opt into only playing your primary lane choice. What I mean by this is that when you play a draft game, you pick a primary and a secondary lane choice (common knowledge, but still); I'm suggesting that I want to be able to play my primary, and there be no chance of getting my secondary. I'd rather wait 10 minutes to get in into a game and play my primary choice, than wait 2 minutes and get my secondary. This seems very confusing, sorry aboot that. Anyways, if you are able to figure out my coded message, what do you think? ;)
