In analysing the champions though, I've discovered that Soraka has hidden jungle potential. Heal and armour steroid keeps her alive easily, and Starcall spam makes short work of the minions. Infuse has roaming and counter-counter-jungling potential, and her ult is global so she can use it to good effect wherever she is. Play her like Ophelia from HoN, except replace minion control (which isn't part of the meta anyway) with a very potent heal/armour buff.
Also, attack speed Janna. Not that good, but certainly not bad either with her shield's AD bonus.
