shes bad

I never play her bot. She's great with some magic or hybrid team mates. And awesome against stealth.

Buy hextech sweeper, Q reveals any stealthers, active on bushes to stop ppl from juking. and lowering their MR

She is good top or bot. Make sure you build her tanky though. Also sometimes thornmail is a better option then frozen heart. I use her a fair bit and win about 75% of the time I play her. I find her very good against AD stacking teams.

Soraka top is D*amn amazing. I don't care what you say especially that first team fight capping top. 2 in q and 1 in e is perfect. silence the best target and spam q all fight. sometime during it, if you've positioned yourself well enough to stay alive you'll level and then get heal and try to get a pro heal in before someone dies. I've had it make a team fight before.
