Que times are up since 6.4 and why? How will they be fixed?

I am silver main mid and jungle which i understand are highly sought after roles which makes for a higher que time. But 8 minutes at silver 1 is ridiculous and diamond players have been getting even higher, my friend Brandon has been getting 30+ minute que times. It's a huge issue that I think needs to be addressed. Also the frequency of having support as your secondary is 18/20 games. I have personally tested this and I enjoy playing support but it's my secondary role for a reason.
