Support Soraka, what do you level first now?

Her Q does a lot less damage so you can't really trade with it and since you have an ADC with you, they can't make use of the debuff most of the time.

Her W has a high mana cost, doesn't heal for that much initially, has a high cooldown, and needs you to level Q some.

Her E now has an offensive mana cost and low damage to go with the "gift mana" cost.

You won't be able to afford a chalice until a few minutes in but you can't start dual charms because you need support items and wards. You know, since you are playing a support and can't start double dorans to use farmed minions to replenish your mana.

So from a support perspective, how do you start soraka out right now?
