I am having on average 10 minute queues in blind pick normals, will this change once im level 30?

No, in fact it will probably get worse. Riot has somehow managed to both increase queue times and decrease matchmaking efficacy simultaneously, all while implementing a system that won't actually give you the position you queue for after removing the system that did.

The width and breadth of incompetence is both staggering and awe inspiring, really. Welcome to season 6.

wrong, it will change

it becomes much faster unless you're plat+

I am in the silver rank, so pretty low, but I usually get matches a min or less
