Old player returning

Hey Guys, It's been quite a while since I actually played League. I've been keeping a touch alittle by watching some streams/youtube videos yet I dont feel at all prepared for the new times. I used to play support in high Plat / Diamond (?). I want to main support again starting now but, what are the meta picks atm? Anything I should know before I dive back into the game. I know runepages are gone. So.. its one of the aspects I didnt like back then. I will await your replies!
