Cant play ranked!

So i have been level 30 for awhile now, i like to practice in normals and play for fun and all, i still dont think I'm that ready for ranked yet but i just wandered why is it locked? both duo/solo and flex, is locked and i can't play them. I know that i need 16 champs like i did with draft pick, but i thought the ones you got in the champ rotation also counted, or am i wrong? do i have to buy 16 champs with ip/rp? i currently have 10 champs btw {{champion:119}}
