Wrong, Soraka is still strong in the end game. She can't save you from getting instantly nuked down, but she allows your team to continue pushing after a team fight by healing/mana restoring your team to full. This is her biggest strength. It's very difficult to break a push that has a Soraka behind it, and her ult gives her whole team an advantage over yours in a fight.
@OP: Soraka is frigging easy to use... cast heal, cast wish, stay in the back and don't die. Repeat. People just don't play her much because support Soraka is rather boring and you never get kills or items. But she doesn't need items when played as a heal/manabot.
