pros

soraka was the best healer of the game
in an team fight pup your ult, summuner spell heal, your heal and silence de ap carrier.

cons
easy to be kill
cannot kill someone in 1 vs 1

Dont farm, do some star fall for the carrier can last hit a maximum of minion.

that was my item, but personally i adapt item in fonction or who i play against. In late game, i change agis of legion for a rabandon because your heal going bether, very bether.

i chose heal because heal is very helpful in team fight and when all your normal spell are in cooldown. Clairvoyance was the support summoner spells per exelence, if you dont have it you are not a real support. You can also chose flash or gost for escape, but your team going to help you if you are good.
