I severely dislike the new ranked system

I don't understand the reasoning. I started as a top laner, but I cant switch unless I want to go through the oh so stressful promos again. And it might just be me, but its even harder to climb out of bronze than before. Can this position ranked system change, it makes it 100% less fun and 100% more chore-like to play ranked. I'm stopping ranked until it reverts.
