What i'd like to see from riot next year regarding placements.

I'd like to see riot release a statement/list preferably stickied to the "help & support" section of the boards detailing how placements are decided etc for me personally i was s5 in season 4, i went 5-5 in my placements and am now b5, i'm not complaining about the ranking or w/e, i'd actually just like to know how riot decides the system (as would pretty much every other ranked player) anybody else feel like this would be a good idea?
