Can we fix dynamic match making to prioritize the primary pick?

Tracked my last 50 matches in dynamic queue (including dodges and whatnot). Here's what I got: Primary: Jungle Secondary: Support

Jungle -> 19 matches Support -> 32 matches

I get Support a little over 60% of the time. I'm fine supporting, but not like 3 times in a row with a random jungle game thrown in. I'm in matchmaking for my diamond promos as I type this, and I can't even play my best role (at least not for the first two games). This is stupid. Can we fix this please?
