is soraka too strong at the moment?

Ok this is not my main account i have an account in G4 atm however i find soraka such a strong bot lane with not many champs that counter her besides maybe annie who have an strong burst instant engage

with the nerf to jungle damage junglers are starting to fall now we see more sustain junglers like zac and nunu who really dont contribute much damage and even less burst damage which we used to get from champs like kha

i understand sorakas weak point which is she cant reliably heal herself but if you spend all your time trying to kill the support by the time she does die the adc already done a great deal of damage and soraka just Q's back to full hp

when i play soraka i just go for HP regen/Tank/CDR and if they focus me thats great they are gonna waste alot of CDs doing it

should her heal CD be increased 1-2 seconds or increase the mana cost? im not sure about what should be done but at the moment i feel once WW gets taken down a notch people will start banning soraka

if im wrong please share what you think im really interested in learning
